Question

The Cooking Club made some pies to sell during lunch to raise money for a field trip. The cafeteria helped by donating five pies to the club. Each pie was then cut into eight pieces and sold. There were a total of 80 pieces to sell. How many pies did the club make?

a) 10 pies
b) 15 pies
c) 8 pies
d) 13 pies

Answer 1

The club made 5 pies. When adding the 5 donated pies, the total number of pies is 10, thus the correct answer is a) 10 pies.

Step-by-step explanation:

To determine the number of pies the Cooking Club made, we need to calculate it based on the total number of pieces they sold. We know that each pie is cut into eight pieces, and the total number of pieces sold was 80. Let's call the number of pies the club made x. Since the cafeteria donated five pies, these pies must be included in our total pie count. Therefore, the equation to solve is:

8*(x + 5) = 80

By solving this equation, we can find the number of pies made by the Cooking Club, excluding the ones donated by the cafeteria:

1. Multiply eight by x (the number of pies made): 8*x
2. Then add the pieces from the donated pies: 8*5 = 40
3. Combine these to match the total number of pieces: 8*x + 40 = 80
4. Solve for x: 8*x = 80 - 40 = 40
5. Divide both sides by 8: x = 40 / 8
6. x = 5

Therefore, the club made 5 pies. If we add the donated pies, the total number of pies is 10. So the correct answer is option a) 10 pies.
