Let's solve each question based on the two pie charts provided in the worksheet.

Part 1: Most Purchased Food

Pie Chart Breakdown:
- Chicken: 26%
- Cheese: 24%
- Hotdogs: 14%
- Pizza: 10%
- Pasta: 11%
- Apples: Remaining (we’ll calculate this)

First, let’s find the percentage for apples:
Total = 100%
So,
> Apples = 100% - (26% + 24% + 14% + 10% + 11%)
> Apples = 100% - 85% = 15%

Now, answer the questions:

---

#### 1) Were chicken and pasta chosen more than hotdogs and pizza, or were they equally bought?

- Chicken: 26%
- Pasta: 11%
- Hotdogs: 14%
- Pizza: 10%

Compare:
- Chicken + Pasta = 26% + 11% = 37%
- Hotdogs + Pizza = 14% + 10% = 24%

✔ Chicken and pasta were chosen more than hotdogs and pizza.

Answer: Chicken and pasta were chosen more.

#### 2) Combined, which two foods did the greatest number of customers buy?

Check all possible pairs:
- Chicken + Cheese = 26% + 24% = 50%
- Chicken + Hotdogs = 26% + 14% = 40%
- Chicken + Pasta = 26% + 11% = 37%
- Chicken + Pizza = 26% + 10% = 36%
- Chicken + Apples = 26% + 15% = 41%
- Cheese + Hotdogs = 24% + 14% = 38%
- Cheese + Pasta = 24% + 11% = 35%
- Cheese + Pizza = 24% + 10% = 34%
- Cheese + Apples = 24% + 15% = 39%
- Hotdogs + Pasta = 14% + 11% = 25%
- etc.

The highest is Chicken + Cheese = 50%

✔ Chicken and cheese had the greatest combined purchase.

Answer: Chicken and cheese

---

#### 3) Between chicken and pasta which food was more popular, or were they equally popular?

- Chicken: 26%
- Pasta: 11%

✔ Chicken was more popular.

Answer: Chicken was more popular.

#### 4) If there were 200 customers that were tracked, how many bought pizza?

Pizza = 10% of 200
= (10/100) × 200 = 20 customers

Answer: 20 customers

---

#### 5) What percent of customers bought either apples or cheese?

Apples = 15%, Cheese = 24%
Total = 15% + 24% = 39%

Answer: 39%

Part 2: Time Spent on Homework

Pie Chart Breakdown:
- English: 30% (Wait — not labeled directly, so we must compute)
Wait — let's check the percentages given:

- History: 22%
- Physics: 11%
- Art: 14%
- Biology: 28%
- Health: 10%

Sum = 22 + 11 + 14 + 28 + 10 = 85%

So English = 100% - 85% = 15%

Now update:
- English: 15%
- History: 22%
- Physics: 11%
- Art: 14%
- Biology: 28%
- Health: 10%

Now answer the questions:

---

#### 1) Between History and Physics which topic took longer, or did they require equal time?

- History: 22%
- Physics: 11%

✔ History took longer.

Answer: History took longer.

---

#### 2) What percentage of time did Chris spend on the English and Health homework?

English: 15%
Health: 10%
Total = 15% + 10% = 25%

Answer: 25%

---

#### 3) Was the History and Physics work or the Biology and Art work longer, or were they equally time consuming?

- History + Physics = 22% + 11% = 33%
- Biology + Art = 28% + 14% = 42%

✔ Biology and Art took longer.

Answer: Biology and Art work was longer.

---

#### 4) If Chris spent 100 minutes on homework, how many minutes were spent on Art?

Art = 14% of 100 minutes
= (14/100) × 100 = 14 minutes

Answer: 14 minutes

---

#### 5) Combined, which two topics required the greatest amount of time?

Check combinations:
- Biology + History = 28% + 22% = 50%
- Biology + English = 28% + 15% = 43%
- Biology + Art = 28% + 14% = 42%
- Biology + Health = 28% + 10% = 38%
- Biology + Physics = 28% + 11% = 39%

Now try History + English = 22% + 15% = 37%
English + Art = 15% + 14% = 29%
etc.

The highest combination is Biology + History = 50%

✔ Biology and History

Answer: Biology and History
