Solve the problem.
-A certain store has a fax machine available for use by its customers. The store charges $2.15 to send the first page and $0.65 for each subsequent page. The total price, P, for the faxing x pages can be modeled by the formula P = 0.65(x - 1) + 2.15. Determine the number of pages that can be faxed for $6.70.
A) 8 pages
B) 50 pages
C) 3 pages
D) 10 pages

To find the number of pages that can be faxed for $6.70, substitute $6.70 for P in the formula and solve for x: $6.70 = 0.65(x - 1) + 2.15. Simplifying, we get $6.70 = 0.65x - 0.65 + 2.15, which simplifies further to $6.70 = 0.65x + 1.50. Subtracting 1.50 from both sides gives $5.20 = 0.65x. Dividing both sides by 0.65 gives x = 8. Therefore, 8 pages can be faxed for $6.70.
