18-ounce box for $3.07
14-ounce box for $2.19
24-ounce box for $3.95
15.5-ounce box for $2.28

Answer 1

To find out which cereal box is the best buy, we need to calculate the price per ounce for each option. We can do this by dividing the price by the number of ounces in each box.

1. **18-ounce box for $3.07:**
\[
\text{Price per ounce} = \frac{3.07}{18} \approx 0.1706 \text{ dollars per ounce}
\]

2. **14-ounce box for $2.19:**
\[
\text{Price per ounce} = \frac{2.19}{14} \approx 0.1564 \text{ dollars per ounce}
\]

3. **24-ounce box for $3.95:**
\[
\text{Price per ounce} = \frac{3.95}{24} \approx 0.1646 \text{ dollars per ounce}
\]

4. **15.5-ounce box for $2.28:**
\[
\text{Price per ounce} = \frac{2.28}{15.5} \approx 0.1471 \text{ dollars per ounce}
\]

Now we can compare the price per ounce for each cereal box:

- 18-ounce box: $0.1706 per ounce
- 14-ounce box: $0.1564 per ounce
- 24-ounce box: $0.1646 per ounce
- 15.5-ounce box: $0.1471 per ounce

The **15.5-ounce box for $2.28**, with a price of approximately $0.1471 per ounce, is the best buy.
