Cherry pie = $11
Pumpkin pie = $12

Explanation:

Let's call cherry pie as c and pumpkin pie as p.

8c + 6p = $160 Eqn 1
8c + 5p = $148 Eqn 2

Subtract Eqn 2 from 1,
cancel(8c) - cancel(8c )+ 6p -5p = 160 - 148
6p - 5p = 160 - 148

p = $12

Substituting value of p in Eqn 1,
8c + (6*12) = 160
8c = 160 - 72
8c = 88
c = $11
