Question

PLZ HELP!

William bought a photocopier and supplies for $162.50, which will allow him to make copies for $0.12 each. A photocopy store charges $0.21 for each copy. How many copies must William make before his total cost is less than getting copies made at the photocopy store?
A) William must make more than 1705 copies.
B) William must make more than 1915 copies.
C) William must make more than 1805 copies.
D) William must make more than 1905 copies.

Answer 1

Your answer would be B. William will pay $392.30 with his, and at the store he'll pay $402.15. :)

Answer 2

The answer is actually C.

Explanation:

Let n represent the number of copies.

William's Copier

Cost ($) is less than Photocopy Store

Cost ($)

162.50 &plus; 0.12n < 0.21n

Therefore, Williams's copying costs will be less than the photocopy store costs when more than 1805 copies are made.
