To find out which bag is cheaper, we can calculate the cost per pound for each option.
1. **40-pound bag for $30.99:**
\[
\text{Cost per pound} = \frac{30.99}{40} = 0.77475 \text{ or about } \$0.775 \text{ per pound}
\]
2. **10-pound bag for $12.98:**
\[
\text{Cost per pound} = \frac{12.98}{10} = 1.298 \text{ or about } \$1.30 \text{ per pound}
\]
Now we compare the two prices:
- 40-pound bag: approximately \$0.775 per pound
- 10-pound bag: approximately \$1.30 per pound
The 40-pound bag is cheaper at about \$0.775 per pound compared to the 10-pound bag at about \$1.30 per pound.
