Question

Brenda and Huong are selling pies for a school fundraiser. Customers can buy cherry pies and lemon meringue pies. Brenda sold 1 cherry pie and 6 lemon meringue pies for a total of $111. huong sold 6 cherry pies and 3 lemon meringue pies for total of $105. What is the cost each of one cherry pie and one lemon meringue pie?

Answer 1

C + 6L = 111

6C+3L = 105

12C + 6L = 210

C + 6L = 111

11C = 99

C = $9 for a cherry pie

6L = 111-9 = 102

L = $17 for a lemon pie

6(9)+3(17) = 54+51 = 104

9+ 6(17) = 9+102 = 111
