2. The owner of a book store buys 120 copies of the newest bestseller for $8 each. She marks up the price of the book by 60%. The store sells 65 books at full price. The owner then discounts the book by 15% off the original selling price. The store sells another 25 books at this price.
Problem A)
What profit has the store made so far on the sale of the books? (Remember, she had to originally buy all the books for $8 a piece).

3. Find the markup and discount price
Answer: $144
See Example:
120(8) = 960-cost of books
Find the markup and discount price
60% markup on $8 = $12.80
15% discount on $12.80 = $10.88
Solve: 65(12.80) + 25 (10.88)
= 1104
= $144
