An online fax company, EFaxIt. com, has a customer plan where a subscriber pays a monthly subscription fee of $11.25 dollars and can send/receive 70 fax pages at no additional cost. For each page sent or received past the 70 page limit, the customer must pay an overage fee of $0.07 per page. The following expression gives the total cost, in dollars, to send P, pages beyond the plan's monthly limit.
C=0.07p+11.25
If the monthly bill under this plan comes out to be $17.97, what was the total number of pages that were sent or received?

  166

Step-by-step explanation:

Put the given information into the formula and solve for p.

  17.97 = 0.07p +11.25

  6.72 = 0.07p . . . . . . . . . . . subtract the subscription fee

  6.72/0.07 = p = 96 . . . . . . divide by the per-page charge

This is the number of additional pages (beyond 70), so ...

   a total of 166 pages were sent or received.

answer: 12,000
