![### Problem Statement
Sara is buying flour for her bake shop. The prices of four types of flour are listed in the table below.
| Type of Flour | Weight | Price |
|---------------|--------|---------|
| Wheat Flour | 5 lb | $12.50 |
| Rice Flour | 8 lb | $24.00 |
| Corn Flour | 15 lb | $33.75 |
| Soy Flour | 24 lb | $55.20 |
**Question:**
Which type of flour costs the least per pound?
**Options:**
A. Wheat flour
B. Rice flour
C. Corn flour
D. Soy flour
---
### Solution Explanation
To find which type of flour is the least expensive per pound, calculate the price per pound for each type of flour:
- **Wheat Flour:**
\( \frac{12.50}{5} = \$2.50 \) per pound
- **Rice Flour:**
\( \frac{24.00}{8} = \$3.00 \) per pound
- **Corn Flour:**
\( \frac{33.75}{15} = \$2.25 \) per pound
- **Soy Flour:**
\( \frac{55.20}{24} = \$2.30 \) per pound
From these calculations, the corn flour costs the least per pound at $2.25. Therefore, the answer is **C. Corn flour**.](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2Fc8c32656-bb06-4bb3-88c2-de84660a623b%2F833d9ec3-a985-49e3-8cd3-7d66a654a9ea%2Fpvarf8_processed.jpeg&w=3840&q=75)
