Answer 1

To determine which store offers the better buy on canned corn, we need to calculate the cost per ounce for both stores.

**For Store A:**
- Price: $1.50 for 15 ounces
- Cost per ounce = \( \frac{1.50}{15} = 0.10 \) dollars per ounce
- Price: $3.00 for 30 ounces
- Cost per ounce = \( \frac{3.00}{30} = 0.10 \) dollars per ounce

So for Store A, the cost per ounce is $0.10.

**For Store B:**
- The equation given is \( y = 0.13x \), where \( y \) is the cost in dollars and \( x \) is the number of ounces.
- To find the cost per ounce, we can see that \( y = 0.13 \) for each ounce.

Thus, the cost per ounce for Store B is $0.13.

**Comparison:**
- Store A: $0.10 per ounce
- Store B: $0.13 per ounce

Now we can determine which store has the better buy:
- Store A's price per ounce ($0.10) is lower than Store B's price per ounce ($0.13) by $0.03.

Thus, the final conclusion is:
**Store A has the better buy by $0.03 per ounce.**
