An online fax company, EFaxdt.com, has a customer plan where a subscriber pays a monthly subscription fee of \( \$ 18.5 \) dollars and can send/receive 80 fax pages at no additional cost. For each page sent or received past the 80 page limit, the customer must pay an overage fee of 50.06 per page. The following expression gives the total cost, in dollars, to send \( p \) pages beyond the plan's monthly limit. \( C=0.06 p+18.5 \) If the monthly bill under this plan comes out to be \( \$ 21.5 \), what was the total number of pages that were sent or received? Answer: The total number of pages sent/received was Next Question

Let \( p \) denote the number of extra pages sent/received beyond the 80-page limit. The total cost is given by \[ C = 0.06p + 18.5. \] Given that the total bill is \( \$21.5 \), we have \[ 0.06p + 18.5 = 21.5. \] **Step 1:** Subtract \( 18.5 \) from both sides: \[ 0.06p = 21.5 - 18.5 = 3. \] **Step 2:** Solve for \( p \) by dividing both sides by \( 0.06 \): \[ p = \frac{3}{0.06} = 50. \] This means \( 50 \) pages were sent/received beyond the monthly limit. **Step 3:** Add the included \( 80 \) pages to the extra \( 50 \) pages to find the total number of pages: \[ \text{Total pages} = 80 + 50 = 130. \] Thus, the total number of pages sent/received was \( 130 \).
