Let’s solve each problem step by step. We’ll calculate sales tax and total cost where needed.
---
Problem 1:
Table costs $45, sales tax is 5%. What is the sales tax?
→ Sales tax = 5% of $45
→ 5% = 0.05
→ 0.05 × 45 =
$2.25
---
Problem 2:
Hat costs $15, sales tax is 10%. How much money do you need to buy it?
→ First, find tax: 10% of $15 = 0.10 × 15 = $1.50
→ Total cost = price + tax = 15 + 1.50 =
$16.50
Wait — let me check the answer choices later. Maybe I misread. The question says “how much money do you need to buy the hat?” That means total cost. But let’s keep going and match with answers at the end.
Actually, looking ahead — maybe some problems ask for tax only, others for total. Let’s be careful.

Problem 3:
Price: $30, Sales Tax: 7%, Total Cost: ?
→ Tax = 7% of 30 = 0.07 × 30 = $2.10
→ Total = 30 + 2.10 =
$32.10
---
Problem 4:
Shoes cost $40, sales tax is 8%. What is the sales tax?
→ Tax = 8% of 40 = 0.08 × 40 =
$3.20
---
Problem 5:
Couch costs $65, sales tax is 6%. What is the sales tax?
→ Tax = 6% of 65 = 0.06 × 65
→ 0.06 × 60 = 3.60, 0.06 × 5 = 0.30 → total = 3.90
→
$3.90
---
Problem 6:
Shirt costs $20, sales tax is 9%. How much money to buy it? (Total cost)
→ Tax = 9% of 20 = 0.09 × 20 = $1.80
→ Total = 20 + 1.80 =
$21.80
---
Problem 7:
Socks cost $4, sales tax is 8%. How much money to buy them? (Total cost)
→ Tax = 8% of 4 = 0.08 × 4 = $0.32
→ Total = 4 + 0.32 =
$4.32
---
Now let’s list all our answers:
1. $2.25
2. $16.50 ← but wait, looking at the answer choices, $16.50 isn’t listed! Did I make a mistake?
Hold on — let’s double-check Problem 2.
Problem 2: Hat costs $15, tax 10%. How much money to buy it? → Should be $16.50.
But in the answer key section, the options are:
Left column:
- $47.25
- $1.80
- $68.90
- $0.32
- $4.32
- $43.20
- $2.25
Right column:
- $1.50
- $32.10
- $16.50 ← here it is!
- $3.20
- $2.10
- $21.80
- $3.90
Ah! So $16.50 IS there — it’s in the right column, third option.
So let’s map each problem to its correct answer from the bubble sheet.
We have 7 problems. The answer sheet has two columns of 7 bubbles each — so we pick one per problem.
Let’s assign:
Problem 1: $2.25 → left column, last option
Problem 2: $16.50 → right column, third option
Problem 3: $32.10 → right column, second option
Problem 4: $3.20 → right column, fourth option
Problem 5: $3.90 → right column, last option
Problem 6: $21.80 → right column, sixth option
Problem 7: $4.32 → left column, fifth option
Wait — let’s verify again:
From our calculations:
1. $2.25
✔
2. $16.50
✔
3. $32.10
✔
4. $3.20
✔
5. $3.90
✔
6. $21.80
✔
7. $4.32
✔
All match the answer choices provided.
Final Answer:
1. $2.25
2. $16.50
3. $32.10
4. $3.20
5. $3.90
6. $21.80
7. $4.32
