Question

The Cooking Club made some pies to sell during lunch to raise money for an end-of-year banquet. The cafeteria contributed three pies to the club. Each pie was then cut into seven pieces and sold. There were a total of 91 pieces to sell. How many pies did the club make?

Answer 1

7x13=91 meaning 13 pies were made in total. Since the cafeteria contributed 3 we can subtract 3 from 13. Ultimately meaning that the club contributed 10 pies.

The answer is 10.
