Answer:

The answer is actually C.

Step-by-step 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.
