Final answer:
The formula to determine the total price for faxing x pages is P = 2.35 + 0.70(x-1). To find the number of pages that can be faxed for $10.75, we solve the equation and find that 13 pages can be faxed.
Step-by-step explanation:
The formula to determine the total price, P, for faxing x pages is: P = 2.35 + 0.70(x-1).
In this formula, the first page is charged $2.35, and each subsequent page is charged $0.70. To find the number of pages that can be faxed for $10.75, we can solve the equation 10.75 = 2.35 + 0.70(x-1) for x.
10.75 - 2.35 = 0.70(x-1)
8.40 = 0.70(x-1)
divide both sides by 0.70
12 = x - 1
add 1 to both sides
13 = x
Therefore, 13 pages can be faxed for $10.75.
