Photography reprints cost $0.52 each at a local photo shop. Through the mail, they cost $0.44 each plus $1.20 postage and handling. How many reprints must a customer purchase to make it less expensive to use mail order? Thanks!

Answer 1

Solve 0.52 X = 0.44 N + 1.20

You can see that you save 8 cents per print at the lower price, but have to make up the $1.20 P&H carge. The answer is X = 1.20/0.08

Answer 2

So then the answer would be x > 15? Thanks!
