Answer 1

The correct response is:

**The 5-lb. bag is the better deal because the unit rate for the 5-lb. bag is less than the unit rate for the 2-lb. bag.**

Here's the reasoning:

- The 2-lb bag costs $1.99, which gives a unit rate of $1.99 / 2 lb = $0.995 per pound.
- The 5-lb bag costs $3.99, which gives a unit rate of $3.99 / 5 lb = $0.798 per pound.

Since $0.798 per pound (the rate for the 5-lb bag) is less than $0.995 per pound (the rate for the 2-lb bag), the 5-lb bag offers better value for money.
