To determine which store has the better buy on footballs, we need to compare the costs at both stores.

From the information provided for Store 1:

  • The cost of 1 football is $12.
  • The cost of 2 footballs is $24 ($12 each).
  • The cost of 3 footballs is $36 ($12 each).

From the graph description provided, it mentions that the points plotted correspond to costs derived from a linear relationship. Specifically:

  • The cost of 1 football should be plotted at (1, 9), meaning $9 per football.
  • The sequential points suggest that each additional football costs an additional $9.

It's important to note that Store 1 is charging $12 per football, based on the tabulated cost structure, while Store 2 seems to be charging $9 per football based on the graph's illustration.

Based on these calculations:

  • Store 1 football cost: $12 each
  • Store 2 football cost: $9 each

Thus, Store 2 has the better buy on footballs:

Store 2 has the better buy on footballs. Store 1’s football costs $12, and Store 2’s football costs $9.
