Let’s solve each problem step by step, using estimation and rounding as the directions specify.

Problem 1:

> In Central City, there are 29,791 registered voters and 93 voting centers. Each voting center serves about ______ of the city’s population.

We need to estimate how many voters each center serves.

Step 1: Round the numbers for easier calculation.
- 29,791 ≈ 30,000 (rounds up to nearest thousand)
- 93 ≈ 90 (rounds down to nearest ten)

Step 2: Divide.
30,000 ÷ 90 = 333.33...

This is closest to 350 among the choices.

✔ Answer: D) 350

*(Note: If you use exact numbers: 29,791 ÷ 93 ≈ 319.8 — still closest to 350.)*

Problem 2:

> At last night’s football game, there were 51,033 fans in attendance. At tonight’s game, there are 44,118 fans in attendance. There are about ______ less fans at tonight’s game than there were at last night’s game.

We need to find the difference and estimate it.

Step 1: Round both numbers.
- 51,033 ≈ 51,000
- 44,118 ≈ 44,000

Step 2: Subtract.
51,000 – 44,000 = 7,000

✔ Answer: B) 7,000

*(Exact difference: 51,033 – 44,118 = 6,915 → rounds to 7,000)*

Problem 3:

> There are 7,213 applicants for the astronaut program. Only one half of the applicants, which is about ______, will be accepted into the program.

We need to estimate half of 7,213.

Step 1: Round 7,213 to 7,200 (easier to halve).

Step 2: Divide by 2.
7,200 ÷ 2 = 3,600

But 3,600 isn’t an option. Let’s check the options:

A) 3,100
B) 3,250
C) 3,400
D) 3,500

Wait — maybe we should round 7,213 to 7,000?

7,000 ÷ 2 = 3,500 → which is an option.

Also, exact half: 7,213 ÷ 2 = 3,606.5 → which is closer to 3,600, but since 3,600 isn’t an option, and 3,500 is the closest available, and 7,213 is closer to 7,000 than 7,200 for estimation purposes? Actually, 7,213 is closer to 7,200.

But let’s see: 7,213 ÷ 2 = 3,606.5 → between 3,500 and 3,600. Since 3,600 isn’t an option, and 3,500 is the closest choice, perhaps that’s intended.

Alternatively, maybe they expect rounding 7,213 to 7,000 → 3,500.

✔ Answer: D) 3,500

*(This is a bit tricky — but 3,500 is the best available estimate.)*

Problem 4:

> Last year, the largest number of pizza orders in one single month was 6,419. The smallest number of pizza orders in one single month was 783. The difference between the largest and smallest order is about...?

Estimate the difference.

Step 1: Round numbers.
- 6,419 ≈ 6,400
- 783 ≈ 800

Step 2: Subtract.
6,400 – 800 = 5,600

✔ Answer: A) 5,600

*(Exact difference: 6,419 – 783 = 5,636 → rounds to 5,600)*

Problem 5:

> Every month, a baker orders 1,182 pounds of flour. About how many pounds of flour does he order each year?

There are 12 months in a year.

Step 1: Round 1,182 to 1,200 (for easy multiplication).

Step 2: Multiply by 12.
1,200 × 12 = 14,400

✔ Answer: C) 14,400

*(Exact: 1,182 × 12 = 14,184 → rounds to 14,200, but 14,400 is the closest given option — wait!)*

Wait — 14,184 is actually closer to 14,200, which is option B.

But we rounded 1,182 → 1,200, so 1,200 × 12 = 14,400.

However, if we round more accurately: 1,182 is closer to 1,180 or 1,200?

1,182 to nearest hundred is 1,200 — yes.

But 1,182 × 12 = 14,184 → which is closer to 14,200 than 14,400.

So which is better?

Let’s check the options:
A) 14,000
B) 14,250
C) 14,400
D) 14,600

14,184 is very close to 14,200, and 14,250 is the closest option.

Wait — 14,184 vs 14,250: difference = 66
vs 14,400: difference = 216 → so 14,250 is much closer.

Perhaps they expect us to round 1,182 to 1,200 → 14,400.

But mathematically, 14,184 is closer to 14,200, and since 14,250 is offered, and 14,200 isn't, 14,250 is the best choice.

Wait — let’s recalculate:

1,182 × 12:

Break it down:
1,000 × 12 = 12,000
180 × 12 = 2,160
2 × 12 = 24
Total = 12,000 + 2,160 = 14,160 + 24 = 14,184

Now, 14,184 is:

- 14,250 – 14,184 = 66 away
- 14,400 – 14,184 = 216 away
- 14,000 – 14,184 = 184 away (but below)

So 14,250 is closest.

✔ Answer: B) 14,250

*(I think the test expects rounding 1,182 to 1,200 → 14,400, but strictly speaking, 14,250 is more accurate. However, looking at the context of “about” and estimation, both could be argued. But since 14,250 is numerically closer, I’ll go with B.)*

Wait — let me check the worksheet again. It says “show all your work”. So perhaps they want rounding before multiplying.

If we round 1,182 to 1,200 → 1,200 × 12 = 14,400 → C

In elementary estimation problems, they usually round first, then compute.

So for consistency with the theme of *estimating*, we should round 1,182 to 1,200.

✔ Final Answer: C) 14,400

*(I think this is what the worksheet expects.)*
