Question

Can you please help me set up this equation?
Copies at the local library cost $.15 easch. A new copier costs $200 and it costs $.02 to make a copy. How many copies would have to be made for the cost of making your own copies equal to the cost of copying at the library?

Thank you!!!!

Answer 1

cost to make n copies at library = .15n
cost to make n copies on your own = 200 + .02n

.15n = 200 + .02n
times 100
15n = 20000+2n
13n = 20000
n = 1538 copies

Answer 2
