Question

Which is the better buy 3 pounds for $8.31 or 5 pounds for $12.95. Explain.

Answer 1

To determine which option is the better buy, we need to calculate the price per pound for each option.

1. **For the 3 pounds for $8.31:**
\[
\text{Price per pound} = \frac{8.31}{3} \approx 2.77
\]

2. **For the 5 pounds for $12.95:**
\[
\text{Price per pound} = \frac{12.95}{5} \approx 2.59
\]

Now, we compare the price per pound:

- 3 pounds for $8.31 costs approximately $2.77 per pound.
- 5 pounds for $12.95 costs approximately $2.59 per pound.

Since $2.59 is less than $2.77, the **5 pounds for $12.95** is the better buy.
