To determine which store has the better buy on footballs, we need to evaluate the cost per football at both stores.

From the information provided, we know:

  • At Store 1, the cost increases in increments. The cost for 1 football is $12, for 2 footballs is $24, and for 3 footballs is $36.
  • At Store 1, the cost per football can be calculated:
    • For 1 football: $12 / 1 = $12
    • For 2 footballs: $24 / 2 = $12
    • For 3 footballs: $36 / 3 = $12 (The cost per football at Store 1 is consistently $12.)

The details for Store 2 are not provided in the initial information, but it states that Store 2's football costs $9.

When comparing the two:

  • Store 1: $12 per football
  • Store 2: $9 per football

Since $9 (Store 2) is less than $12 (Store 1), Store 2 has the better buy on footballs.

Thus, the correct response is: Store 2 has the better buy on footballs. Store 1’s football costs $12, and Store 2’s football costs $9.
