Find the cost each of one blueberry pie and one lemon meringue pie.

Question

Totsakan and Beth are selling pies for a school fundraiser. Customers can buy blueberry pies and lemon meringue pies. Totsakan sold 9 blueberry pies and 3 lemon meringue pies for a total of $99. Beth sold 7 blueberry pies and 10 lemon meringue pies for a total of $169. Find the cost each of one blueberry pie and one lemon meringue pie.

We need to find out what x and y represents and the system of equations.

Answer 1

qty x unit price = the total price for each fruit.

Let B be blueberry and L be lemon

9B + 3L = 99

7B + 10L = 169

Use substitution method to solve for B and L

B = 7

L = 12
