Math

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!!!!

  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
