## SECTION 1: Most Purchased Food (Grocery Store Pie Graph)

Pie Chart Data:

- Cheese: 24%
- Chicken: 26%
- Hotdogs: 14%
- Apples: ? (not given — but we can calculate)
- Pasta: 11%
- Pizza: 10%

> *Note: The percentages must add up to 100%. Let’s check:*
> 24% + 26% + 14% + 11% + 10% = 85%
> → So apples = 100% - 85% = 15%

✔ Corrected Full Breakdown:
- Cheese: 24%
- Chicken: 26%
- Hotdogs: 14%
- Apples: 15%
- Pasta: 11%
- Pizza: 10%

---

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

- Chicken + Pasta = 26% + 11% = 37%
- Hotdogs + Pizza = 14% + 10% = 24%
→ 37% > 24%

Answer: Chicken and pasta were chosen MORE than hotdogs and pizza.

Question 2: Combined, which two foods did the greatest number of customers buy?

We need to find the two largest individual percentages:

- Chicken: 26% ← highest
- Cheese: 24% ← second highest

Combined: 26% + 24% = 50% — the largest possible pair.

Answer: Chicken and cheese

---

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

- Chicken: 26%
- Pasta: 11%

26% > 11%

Answer: Chicken was more popular.

---

Question 4: If there were 200 customers that were tracked, how many bought pizza?

Pizza = 10% of 200

→ 10% × 200 = 0.10 × 200 = 20 customers

Answer: 20

---

Question 5: What percent of customers bought either apples or cheese?

Apples = 15%, Cheese = 24%

→ 15% + 24% = 39%

Answer: 39%

## SECTION 2: Time Spent on Homework (Chris’s Pie Graph)

Pie Chart Data:

- English: ? (not given — calculate)
- History: 22%
- Physics: 11%
- Art: 14%
- Biology: 28%
- Health: 10%

> Total must be 100%:
> 22% + 11% + 14% + 28% + 10% = 85%
> → English = 100% - 85% = 15%

✔ Corrected Full Breakdown:
- English: 15%
- History: 22%
- Physics: 11%
- Art: 14%
- Biology: 28%
- Health: 10%

---

Question 1: Between History and Physics which topic took longer; or did they require equal time?

- History: 22%
- Physics: 11%

22% > 11%

Answer: History took longer.

---

Question 2: What percentage of time did Chris spend on the English and Health homework?

English = 15%, Health = 10%

→ 15% + 10% = 25%

Answer: 25%

---

Question 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%

42% > 33%

Answer: Biology and Art work took longer.

---

Question 4: If Chris spent 100 minutes on homework, how many minutes were spent on Art?

Art = 14% of 100 minutes

→ 0.14 × 100 = 14 minutes

Answer: 14

---

Question 5: Combined, which two topics required the greatest amount of time?

Find the two largest percentages:

- Biology: 28% ← highest
- History: 22% ← second highest

Combined: 28% + 22% = 50% — the largest possible pair.

Answer: Biology and History
