Final answer:
The cafeteria contributed 2 pies of pizza to the sale. Chef made an additional 6 pies to sell at the basketball game.
Step-by-step explanation:
The cafeteria contributed 2 pies of pizza to the sale. Each pie was then cut into 6 pieces, resulting in a total of 12 slices per pie. Therefore, there were 2 pies x 12 slices = 24 slices from the initial contribution. If there were a total of 60 slices to sell, then the remaining slices were made by Chef. To find out how many pies Chef made, we subtract the slices from the initial contribution from the total slices: 60 slices - 24 slices = 36 slices.
Since each pie is cut into 6 pieces, we divide the remaining slices by 6 to find out how many pies Chef made: 36 slices ÷ 6 = 6 pies.
Therefore, Chef made 6 pies of pizza to sell at the basketball game.
