Let’s go through each problem one by one. We’ll match the word problem to its correct answer by solving it step by step.

---

Problem 1:
*Kathy saves $2.50 every day in 60 days. How many dollars will she have in 18 days?*

→ She saves $2.50 per day.
→ In 18 days: 2.50 × 18 = ?

Let’s calculate:
2.50 × 18 = (2 × 18) + (0.50 × 18) = 36 + 9 = 45

✔ Answer: d. 45

---

Problem 2:
*A car company is projected to increase sales by 15% next year. If they sold 70 cars this year, how many are projected next year?*

→ 15% of 70 = 0.15 × 70 = 10.5
→ Next year’s sales = 70 + 10.5 = 80.5

But wait — you can’t sell half a car. Maybe we round? But looking at the options, none say 80.5. Let’s check the options again:

Options:
a. 12.24
b. 78.75
c. 8
d. 45
e. 7.5
f. 25
g. 125
h. 3
i. 4000
j. 1250

Wait — maybe I misread. Is it possible the question meant “increase BY 15%” but the answer choices don’t include 80.5? That suggests maybe there’s a typo or I need to recheck.

Wait — let me recalculate:
15% of 70 = 10.5 → 70 + 10.5 = 80.5 — still not matching any option.

Hold on — perhaps the question was supposed to be “increase TO 15%”? No, that doesn’t make sense.

Alternatively — maybe it’s 15% *of* something else? Or maybe the original number is different?

Wait — look at option b: 78.75 — that’s 70 + 8.75. What’s 8.75 as % of 70? 8.75 / 70 = 0.125 → 12.5%. Not 15%.

Hmm. Maybe I made a mistake.

Wait — what if the question said “increase by 12.5%”? Then 12.5% of 70 = 8.75 → 78.75 → matches option b.

But the problem says 15%. Unless… maybe it’s a trick? Or maybe I should just go with the math.

Actually — let’s double-check the problem statement from the image description. The user wrote:

> A car company is projected to increase sales by 15% next year. If they sold 70 cars this year, how many are projected next year?

And options include b. 78.75 — which is NOT 15% increase.

Wait — unless... maybe it's 15% of last year’s profit or something? No, it says "sales".

Perhaps there’s an error in the worksheet? But since we must choose from given answers, and 80.5 isn’t there, maybe I miscalculated.

Wait — 15% of 70:

10% of 70 = 7
5% of 70 = 3.5
So 15% = 10.5 → total 80.5 — still no match.

Unless… maybe the question is “how much did sales INCREASE?” — then it would be 10.5 — still not in options.

Option e is 7.5 — too low. Option f is 25 — too high.

Wait — maybe the base is not 70? Let me read again.

No — it says “sold 70 cars this year”.

This is confusing. Let’s skip for now and come back.

Actually — looking at the answer key pattern, maybe problem 2 is matched to b. 78.75 — which would mean the increase was 12.5%, not 15%. Perhaps a typo in the problem? Since we have to pick from options, and 78.75 is closest to a reasonable calculation if it were 12.5%, but the problem says 15%.

Wait — another thought: maybe “projected to increase sales by 15%” means the new sales are 115% of old, so 1.15 × 70 = 80.5 — still not matching.

I think there might be a mistake in the worksheet or my reading. But let’s assume for now that perhaps the intended answer is b. 78.75, implying a 12.5% increase — maybe a typo. We’ll note that and move on.

Actually — let’s check other problems first.

Problem 3:
*Ronalda’s furniture house is currently producing 100 chairs a day. How many chairs should it produce if it wants to meet a demand that is twice its current production?*

→ Twice 100 = 200 — but 200 is not in the options.

Options: a.12.24, b.78.75, c.8, d.45, e.7.5, f.25, g.125, h.3, i.4000, j.1250

None is 200. Wait — maybe “twice its current production” means add 100 more? Still 200.

Unless… “meet a demand that is twice” — so produce 200. But not in options.

Wait — option g is 125 — that’s 25% more. Option j is 1250 — way too big.

This is strange. Maybe I misread.

“currently producing 100 chairs a day. How many chairs should it produce if it wants to meet a demand that is twice its current production?”

Twice 100 is 200. Not in options.

Unless “twice its current production” means something else? Like, demand is twice, so they need to produce 200. Still not matching.

Perhaps the question is “how many MORE chairs”? Then 100 — not in options.

Wait — option c is 8 — too small. Option h is 3 — no.

Maybe it’s a different interpretation. Or perhaps the number is not 100? Let me check the user input.

User wrote: “Ronalda’s furniture house is currently producing 100 chairs a day.”

Yes.

This is problematic. Let’s skip and come back.

Problem 4:
*Karen’s car requires 5 liters of diesel to cover a distance of 60 km. How many liters of diesel will Karen need if she has to cover 125 kilometers?*

→ First, find fuel per km: 5 liters / 60 km = 1/12 liter per km
→ For 125 km: 125 × (1/12) = 125/12 ≈ 10.4167 — not in options.

Options: e.7.5, f.25, etc.

125/12 = 10.4167 — not matching.

Wait — maybe ratio: 5 liters for 60 km, so for 125 km: (5/60)*125 = (1/12)*125 = 125/12 ≈ 10.42 — still not in options.

Option e is 7.5 — that’s for 90 km? 5/60 = x/90 → x=7.5 — yes! But the question is for 125 km.

Unless I miscalculated.

(5 liters / 60 km) = x liters / 125 km
x = (5 * 125) / 60 = 625 / 60 = 125/12 = 10.4167 — same.

Not in options. Option f is 25 — too big. Option g is 125 — way bigger.

This is not working. Perhaps the distance is different? User said 125 km.

Wait — maybe it's 75 km? Then (5/60)*75 = 6.25 — not 7.5.

For 90 km: (5/60)*90 = 7.5 — which is option e.

But the problem says 125 km. Unless typo.

Perhaps "cover 125 kilometers" is wrong, and it's 90? But user wrote 125.

Let's assume for now that it's 90 km, then answer is 7.5 — option e.

But that's guessing.

Another idea: maybe "5 liters for 60 km", so for 125 km, how many liters? Proportion: 5/60 = x/125 -> x= (5*125)/60 = 625/60 = 125/12 = 10.4167 — not in options.

Option e is 7.5 — which is for 90 km.

Perhaps the problem is "how many liters for 75 km"? 5/60 = x/75 -> x= (5*75)/60 = 375/60 = 6.25 — not 7.5.

For 90 km: 7.5 — yes.

I think there might be a typo in the problem or options. But let's look at the answer choices; perhaps for problem 4, it's e.7.5, assuming the distance is 90 km.

But the user said 125 km. This is frustrating.

Let's try problem 5.

Problem 5:
*Will sells 35 bags of corn in a day. How many kilograms will he sell if he has to sell 35 bags per day?*

Wait — it says "sells 35 bags", and "how many kilograms will he sell if he has to sell 35 bags per day?" — that seems redundant.

Probably missing information: how many kg per bag?

Looking at options, f.25 is there.

Perhaps each bag is 25 kg? But not stated.

The problem as written: "Will sells 35 bags of corn in a day. How many kilograms will he sell if he has to sell 35 bags per day?"

It doesn't specify weight per bag. So we can't solve without that.

Unless in the context, it's implied. Or perhaps it's a trick — if he sells 35 bags, and each bag is 1 kg, then 35 kg — not in options.

Option f is 25 — close but not 35.

Option g is 125 — too big.

This is not working.

Perhaps "35 bags" and each bag is 25/35 kg? Nonsense.

I think there's missing info. But let's assume that each bag is 25/35 kg? No.

Another idea: perhaps "how many kilograms" and the answer is 25, meaning each bag is approximately 0.714 kg — unlikely.

Perhaps the problem is "he sells 35 bags, and each bag weighs 25/35 kg" — but that's silly.

Let's look at the options; perhaps for problem 5, it's f.25, and we'll see later.

---

Problem 6:
*Jeff has a big scoop of ice cream that is 10 inches tall. It melts by 25% in a minute. What's the height of ice cream after one minute?*

→ 25% of 10 inches = 2.5 inches melted
→ Remaining height = 10 - 2.5 = 7.5 inches

✔ Answer: e. 7.5

Good, this matches.

---

Problem 7:
*Jenny uses 7 meters of string to tie her present. How much string does she need if she wanted to tie the box for a length of 3 meters?*

This is confusing. "uses 7 meters to tie her present" — probably for a certain size. "if she wanted to tie the box for a length of 3 meters" — what does "length of 3 meters" mean? The box size?

Probably, it's proportional. If for a box of size X, she uses 7m, then for a box of size 3m, how much?

But what is the unit? Perhaps the "length" refers to the dimension of the box.

Assume that the string needed is proportional to the size of the box.

If for a box of size S, she uses 7m, then for size 3m, she uses (3/S)*7 — but S is not given.

Perhaps "tie the box for a length of 3 meters" means the perimeter or something.

Another interpretation: perhaps "7 meters of string to tie her present" means for a standard present, and now she wants to tie a box that is 3 meters in some dimension, but we need more info.

Look at options: h.3 is there.

Perhaps it's direct: if she wants to tie for 3 meters, she needs 3 meters of string? But that ignores the 7 meters.

The problem says: "Jenny uses 7 meters of string to tie her present." — so for one present, 7m.

"How much string does she need if she wanted to tie the box for a length of 3 meters?"

Perhaps "for a length of 3 meters" means the box has a length of 3 meters, and we assume that the string needed is proportional to the length.

But what was the length of the original present? Not given.

Unless "her present" is assumed to be 1 meter or something.

Perhaps it's a ratio: if for length L, she uses 7m, then for length 3m, she uses (3/L)*7 — but L unknown.

This is ambiguous.

Option h is 3 — perhaps they mean she needs 3 meters for a 3-meter box, ignoring the 7 meters? But that doesn't make sense.

Another idea: perhaps "tie the box for a length of 3 meters" means she wants the string to be 3 meters long, so she needs 3 meters — but why mention 7 meters?

I think there's a mistake in the problem statement.

Perhaps "7 meters" is for a box of size 7 meters, and now for 3 meters, she needs 3 meters — so answer h.3.

That could be it. Assume that the string length equals the box length for tying.

So for a 3-meter box, she needs 3 meters of string.

✔ Answer: h. 3

---

Problem 8:
*The price of Gary's favorite skate board is $400. Now, the price is expected to rise by 25%. How much money will he save if he buys it now?*

→ Rise by 25% means new price = 400 + 25% of 400 = 400 + 100 = $500
→ If he buys now, he pays $400 instead of $500, so he saves $100.

But $100 is not in the options.

Options: i.4000, j.1250 — both larger.

25% of 400 is 100 — save $100.

Not in options. Option i is 4000 — too big. j is 1250 — also big.

Perhaps "save" means something else? Or perhaps the rise is 25% of something else.

Another interpretation: "expected to rise by 25%" — so future price is 125% of 400 = 500, so saving by buying now is 100.

Still not in options.

Unless the question is "how much will he pay if he buys later?" — 500, not in options.

Or "how much is the increase?" — 100, not in options.

Option j is 1250 — 125% of 1000? Not related.

Perhaps the price is $400, rise by 25%, so increase is 100, but maybe they want the new price minus old, which is 100.

I think there's a mistake. But let's see the options; perhaps for problem 8, it's i.4000 or j.1250, but that doesn't make sense.

Another thought: "how much money will he save" — if he buys now, he saves the amount of the increase, which is 100.

But 100 not in options. Option f is 25 — too small. g is 125 — close to 100? No.

Perhaps the price is $5000 or something, but it's $400.

Let's calculate 25% of 400 = 100.

Perhaps "save" means the difference, but maybe they want the new price: 500 — not in options.

I recall that in some contexts, "save" might be misinterpreted, but here it's clear.

Perhaps the rise is 25% of the new price? But that would be unusual.

If rise by 25% of new price, then let new price be P, then P = 400 + 0.25P -> 0.75P = 400 -> P = 400 / 0.75 = 533.33, save 133.33 — not in options.

Still not.

Option j is 1250 — 125% of 1000, not related.

Perhaps the price is $5000, but it's written as $400.

I think there might be a typo in the problem or options.

But let's look back at problem 2.

For problem 2: car company, 70 cars, increase by 15% -> 80.5, not in options.

But option b is 78.75, which is 70 * 1.125 = 78.75, so 12.5% increase.

Perhaps the problem said 12.5% but user typed 15%? Or vice versa.

Similarly, for problem 3: produce twice current, 200, not in options, but option g is 125, which is 25% more than 100.

For problem 4: 5 liters for 60 km, for 125 km, should be 10.42, but option e is 7.5, which is for 90 km.

For problem 5: 35 bags, how many kg — if each bag is 25/35 kg, but that's not integer.

Perhaps for problem 5, "how many kilograms" and the answer is 25, assuming each bag is 25/35 kg, but that's messy.

Another idea for problem 5: perhaps "35 bags" and each bag is 25 kg, but then 35*25=875, not in options.

Option f is 25 — perhaps they mean per bag or something.

I think I need to match based on common mistakes or typical errors.

Let's list the problems and likely answers based on calculation:

1. Kathy: 2.50 * 18 = 45 -> d.45

2. Car company: 70 * 1.15 = 80.5 — not in options, but 70 * 1.125 = 78.75 -> b.78.75 (assuming 12.5% increase)

3. Furniture: twice 100 = 200 — not in options, but 100 * 1.25 = 125 -> g.125 (assuming 25% increase, not twice)

4. Karen: (5/60)*125 = 10.42 — not in options, but (5/60)*90 = 7.5 -> e.7.5 (assuming 90 km)

5. Will: 35 bags — if each bag is 25/35 kg, but that's not good. Perhaps "how many kilograms" and the answer is 25, so maybe each bag is 25/35 kg, but that's approximately 0.714, not nice. Option f.25 — perhaps they mean the weight per bag is 25/35, but the total is 25 kg for 35 bags? 25/35 = 5/7 kg per bag, then for 35 bags, 25 kg — oh! If the total weight is 25 kg for 35 bags, then he sells 25 kg.

The problem says: "Will sells 35 bags of corn in a day. How many kilograms will he sell if he has to sell 35 bags per day?"

It doesn't specify the weight, but perhaps it's implied that the 35 bags weigh 25 kg in total. Or perhaps in the context, it's given that each bag is a certain weight, but not stated.

If we assume that the 35 bags correspond to 25 kg, then answer is 25 kg.

So f.25

6. Jeff: 10 - 25% of 10 = 7.5 -> e.7.5

7. Jenny: if for a box of size 7 meters, she uses 7m string, then for 3 meters, she uses 3m -> h.3

8. Gary: save 25% of 400 = 100 — not in options, but option i.4000 or j.1250. 25% of 5000 = 1250, so perhaps the price is $5000, but it's written as $400. Or "rise by 25%" and save the increase, but 100 not there.

Option j is 1250 — 25% of 5000 = 1250, so if price was $5000, save $1250.

But it's $400.

Perhaps "the price is expected to rise by 25%" and "how much will he save" — if he buys now, he saves the future increase, which is 100, but not in options.

Another possibility: "how much money will he save" might mean how much less he pays, which is 100, but perhaps they want the new price minus old, which is 100.

I think for problem 8, it might be j.1250, assuming a typo in price.

But let's see the options left.

After assigning:

1. d.45

2. b.78.75 (assuming 12.5%)

3. g.125 (assuming 25% increase, not twice)

4. e.7.5 (assuming 90 km)

5. f.25 (assuming 35 bags = 25 kg)

6. e.7.5 — but e is already used for 4? No, options can be reused? In matching, usually each answer is used once, but here there are 8 problems and 10 options, so some options may not be used, or some used multiple times? The instruction is "match the word problems to their answers", and there are 8 problems and 10 options, so probably each problem has a unique answer, and two options are distractors.

In the user input, options are a to j, 10 options, 8 problems, so two will not be used.

In my assignment, I have:

1. d

2. b

3. g

4. e

5. f

6. e — conflict, e used twice.

Problem 6 is also e.7.5, but problem 4 is also e.7.5 — can't be.

So for problem 4, if it's 125 km, it should be 10.42, not 7.5.

Perhaps for problem 4, it's different.

Let's recalculate problem 4: "Karen’s car requires 5 liters of diesel to cover a distance of 60 km. How many liters of diesel will Karen need if she has to cover 125 kilometers?"

5/60 = x/125 -> x = 5*125/60 = 625/60 = 125/12 = 10.4167

Not in options. Option g is 125 — too big. Option j is 1250 — bigger.

Perhaps "cover 125 kilometers" is a typo, and it's 75 km? 5/60 = x/75 -> x=6.25 — not in options.

Or 90 km: 7.5 — option e.

But then problem 6 is also 7.5.

Unless problem 6 is not 7.5.

Problem 6: ice cream 10 inches, melts 25%, so 7.5 inches — definitely 7.5.

So both 4 and 6 would be 7.5, but only one e.

So perhaps for problem 4, it's different.

Another idea for problem 4: perhaps "5 liters for 60 km", so for 125 km, but maybe they want the additional liters or something.

Or perhaps the answer is 125/12, but not in options.

Let's look at option a.12.24 — close to 12.5, but not.

125/12 = 10.4167, not 12.24.

Perhaps it's 5 liters for 60 km, so rate is 12 km per liter, then for 125 km, 125/12 = 10.4167 liters.

Same.

I think I need to accept that for problem 4, it's e.7.5, and for problem 6, it's also e.7.5, but that can't be in a matching exercise.

Unless the options are not unique, but typically they are.

Perhaps for problem 6, "melts by 25%" means the height becomes 25% of original, so 2.5 inches, but that would be option not there, and 2.5 not in options.

The problem says "melts by 25%", which means reduces by 25%, so 75% left, 7.5 inches.

So must be 7.5.

For problem 4, perhaps the distance is 90 km, and the 125 is a typo.

Or perhaps "125 kilometers" is for something else.

Another thought: in problem 4, "cover 125 kilometers" but perhaps it's 12.5 km? Then 5/60 = x/12.5 -> x= (5*12.5)/60 = 62.5/60 = 1.0417 — not in options.

Or 75 km: 6.25 — not.

Let's calculate what distance gives 7.5 liters: from 5/60 = 7.5/x -> x = (7.5*60)/5 = 450/5 = 90 km.

So if the problem said 90 km, answer is 7.5.

Probably a typo, and it's 90 km.

Similarly, for problem 2, likely 12.5% increase.

For problem 3, "twice" might be "25% more" or something.

For problem 5, "35 bags" and "25 kg" total.

For problem 8, perhaps the price is $5000, rise by 25%, save $1250.

Let's assume that.

So let's finalize:

1. Kathy: 2.50 * 18 = 45 -> d.45

2. Car company: 70 * 1.125 = 78.75 -> b.78.75 (assuming 12.5% increase)

3. Furniture: 100 * 1.25 = 125 -> g.125 (assuming 25% increase, not twice)

4. Karen: for 90 km, 7.5 liters -> e.7.5 (assuming 90 km instead of 125)

5. Will: 35 bags = 25 kg -> f.25

6. Jeff: 10 * 0.75 = 7.5 -> but e is already used, and 7.5 is e, but we have only one e.

Problem 6 is also 7.5, so conflict.

Unless for problem 6, it's different.

Perhaps "melts by 25%" means the volume or something, but height is linear, so should be proportional.

Or perhaps "after one minute" and it melts continuously, but still, 25% of height.

I think the only way is to have problem 4 and 6 both require 7.5, but since it's matching, perhaps the worksheet allows it, or perhaps I have a mistake.

Let's check problem 7: Jenny uses 7 meters for her present, wants to tie for length 3 meters — if we assume that the string needed is proportional to the size, and if her present is 7 meters in size, then for 3 meters, 3 meters string -> h.3

Problem 8: Gary, price $400, rise 25%, save $100 — not in options, but if price is $5000, save $1250 -> j.1250

Then options used: d,b,g,e,f,h,j — that's 7, need 8.

Problem 3 is g.125, problem 5 is f.25, etc.

List:

1. d.45

2. b.78.75

3. g.125

4. e.7.5

5. f.25

6. ? 7.5, but e taken

7. h.3

8. j.1250

So for problem 6, what is left? Options left: a.12.24, c.8, i.4000

None is 7.5.

Perhaps for problem 6, "melts by 25%" means the height is reduced to 25%, so 2.5 inches, not in options.

Or perhaps "after one minute" and it melts at a rate, but still.

Another idea: perhaps "10 inches tall" and "melts by 25%" means the melt rate is 25% per minute, so after 1 minute, height is 10 * (1-0.25) = 7.5, same as before.

I think I have to conclude that for problem 6, it's e.7.5, and for problem 4, it's something else.

Let's swap.

Suppose for problem 4, with 125 km, answer is 125/12 = 10.4167, not in options, but option a is 12.24 — close to 12.5, not.

Perhaps it's 5 liters for 60 km, so for 125 km, but maybe they want the number of liters as 125/10 = 12.5, but not.

Let's calculate 5/60 = 1/12, 125/12 = 10.4167.

Option c is 8 — not close.

Perhaps "cover 125 kilometers" is the total, but she already covered some, but not specified.

I recall that in some problems, "requires 5 liters for 60 km" means consumption rate, and for 125 km, it's (5/60)*125 = 10.4167, and perhaps they expect 10.4, but not in options.

Option a is 12.24 — let's see what that corresponds to.

12.24 / 5 = 2.448, 2.448 * 60 = 146.88 km — not 125.

Perhaps it's inverse.

Another thought: perhaps "5 liters for 60 km" means efficiency 12 km/L, so for 125 km, 125/12 = 10.4167 L.

Same.

I think for the sake of completing, I'll assign problem 6 to e.7.5, and for problem 4, since 125 km, and 5/60 = x/125, x=10.4167, and option a is 12.24, which is close to 12.5, but not.

Perhaps the distance is 146.88 km for 12.24 liters, but not.

Let's look at problem 8 again.

" The price of Gary's favorite skate board is $400. Now, the price is expected to rise by 25%. How much money will he save if he buys it now?"

Save the amount of the increase, which is 100.

But 100 not in options. Option i is 4000, j is 1250.

25% of 5000 = 1250, so if price was $5000, save $1250.

Perhaps " $400" is a typo, and it's $5000.

Or "rise by 25%" and "save" means the future price minus current, which is 100, but perhaps they want the future price: 500, not in options.

Another interpretation: "how much money will he save" might mean how much he has to pay less, which is 100, but perhaps in the context, "save" means the discount or something.

I think the most reasonable is to assume for problem 8, it's j.1250, assuming price is $5000.

Then for problem 6, e.7.5.

For problem 4, with 125 km, perhaps it's not 7.5, but let's see what option is left.

After assigning:

1. d.45

2. b.78.75

3. g.125

5. f.25

6. e.7.5

7. h.3

8. j.1250

Then problem 4 is left, and options left: a.12.24, c.8, i.4000

For problem 4: 5 liters for 60 km, for 125 km, x = 5*125/60 = 625/60 = 125/12 = 10.4167

Closest is a.12.24 or c.8 — 10.4 is closer to 12.24? No, 10.4 - 8 = 2.4, 12.24 - 10.4 = 1.84, so closer to 12.24, but not very close.

Perhaps it's 5 liters for 60 km, so for 1 km, 5/60 L, for 125 km, 125*5/60 = 625/60 = 125/12 = 10.4167

Or perhaps they want it as fraction, but not.

Another idea: perhaps "cover 125 kilometers" but the 5 liters is for a different distance.

Or perhaps the car requires 5 liters to cover 60 km, so to cover 125 km, but maybe they mean the additional distance or something.

I think for problem 4, it might be c.8, but 8 is not close.

Let's calculate if it were 96 km: 5/60 = x/96 -> x=8, yes! 5/60 = 1/12, 96/12 = 8.

So if the distance was 96 km, answer is 8.

Probably a typo, and it's 96 km instead of 125 km.

So assume that.

Then problem 4: c.8

Then all assigned.

So summary:

1. d.45

2. b.78.75

3. g.125

4. c.8 (assuming 96 km)

5. f.25

6. e.7.5

7. h.3

8. j.1250 (assuming price $5000)

And options a.12.24 and i.4000 not used.

Now for problem 3, "twice its current production" — we assumed 25% increase to 125, but twice is 200, not 125. But 125 is 25% more, not twice.

Perhaps "meet a demand that is twice" means they need to produce 200, but 200 not in options, so likely "twice" is a mistake, and it's "25% more" or "increase by 25%".

Similarly for others.

So I'll go with that.

Final matching:

1. d

2. b

3. g

4. c

5. f

6. e

7. h

8. j

Now to write the answer.

But for the student, I should explain each briefly.

Since the user asked to solve accurately, and with the assumptions, I'll provide the answers.

So for each problem:

1. Kathy: 2.50 * 18 = 45 → d

2. Car company: 70 * 1.125 = 78.75 → b (assuming 12.5% increase)

3. Furniture: 100 * 1.25 = 125 → g (assuming 25% increase)

4. Karen: for 96 km, (5/60)*96 = 8 → c (assuming 96 km)

5. Will: 35 bags = 25 kg → f

6. Jeff: 10 * 0.75 = 7.5 → e

7. Jenny: for 3 meters, 3 meters string → h

8. Gary: if price $5000, 25% of 5000 = 1250 saved → j

So the matches are:

1-d, 2-b, 3-g, 4-c, 5-f, 6-e, 7-h, 8-j

Now for the final answer, since it's matching, I need to list the letter for each problem.

The user didn't specify how to output, but probably list the answer for each.

Since the instruction is "solve the problem accurately", and it's a matching, I'll provide the pairs.

But in the response, I can say:

Here are the correct matches:

Problem 1: d. 45

Problem 2: b. 78.75

Problem 3: g. 125

Problem 4: c. 8

Problem 5: f. 25

Problem 6: e. 7.5

Problem 7: h. 3

Problem 8: j. 1250

With the understanding that there are typos in the problems, but based on the options, this is the best fit.

For the student, I should explain the calculations as per the intended problems.

So in the explanation, I'll assume the corrected versions.

Let's do that.

Explanation for each:

1. Kathy saves $2.50 per day. In 18 days: 2.50 × 18 = 45 dollars. So answer is d.45.

2. Car company sold 70 cars. If sales increase by 12.5% (not 15%, as 15% gives 80.5 not in options), then increase = 70 × 0.125 = 8.75, so new sales = 70 + 8.75 = 78.75. So answer is b.78.75.

3. Furniture house produces 100 chairs. If they want to meet demand that is 25% more (not twice, as twice is 200 not in options), then 100 × 1.25 = 125 chairs. So answer is g.125.

4. Karen's car uses 5 liters for 60 km. For 96 km (not 125 km, as 125 gives 10.42 not in options), liters needed = (5/60) × 96 = (1/12) × 96 = 8 liters. So answer is c.8.

5. Will sells 35 bags of corn, and if the total weight is 25 kg, then he sells 25 kg. So answer is f.25.

6. Jeff's ice cream is 10 inches tall. Melts by 25%, so melts 2.5 inches, remaining height = 10 - 2.5 = 7.5 inches. So answer is e.7.5.

7. Jenny uses 7 meters of string for her present. If she wants to tie a box of length 3 meters, and assuming string needed is proportional to size, and if her present is 7 meters, then for 3 meters, she needs 3 meters of string. So answer is h.3.

8. Gary's skateboard is $400, but if we assume it's $5000 (as $400 gives save $100 not in options), then rise by 25% = 0.25 × 5000 = 1250, so he saves $1250 by buying now. So answer is j.1250.

So the final answer is the matching as above.

For the boxed answer, since it's multiple, perhaps list the letters.

But the instruction is "Final Answer: [Provide only the final correct answer]", so perhaps for each problem, but it's a set.

Since it's a matching worksheet, the answer is the pairings.

I think for the response, I'll state the matches.

So Final Answer:

1. d
2. b
3. g
4. c
5. f
6. e
7. h
8. j

With the explanations above.

To comply with the format, I'll put that in Final Answer.

But let's confirm if there's a better way.

Perhaps for problem 8, "how much money will he save" means the amount he saves by buying now, which is the increase, 100, but since not in options, and 1250 is there, likely typo.

Similarly for others.

I think it's acceptable.

So I'll go with that.
