Question

The cost of a Black Forest cake at two bakeries is as follows: Julie's Bakery: cost $15, delivery charge $0.20 per mile; Bakers Hut: cost $20, delivery charge $0.15 per mile. Find the distance for which the two bakeries charge the same price for the Black Forest cake

Answer 1

15 + 0.2x = 20 + 0.15x
0.05x = 5
x = 100 miles
