8 textbooks cost $124. if each textbook was sold for 17, what is the profit made on one book?
First, find the cost for each textbook by dividing the total cost by the number of textbooks:
$124.00 ÷ 8 = $ 15.50
Second, find the difference between what you sold it for and what you paid for it:
$17.00 - $15.50 = profit made on each book.
