Answer 1

The cost of an apple pie is $13 and a blackberry pie is $18.

How to find the cost?

Let A be apple pies and B be blackberry pies.

3A + 11B = $237

3A + 12B = $255.

On solving the quadratic equation, we get

-B = -18

Therefore,

B = 18

Substitute B in any one of the equations,

3A + 11*18 = 237

3A = 237 - 198

A = 39/3

A = 13

The cost of an apple pie is $13 and a blackberry pie is $18.
