[Question]Connor wanted to order some new books to read. The website was offering free shipping over $50.00. They also had a deal that when you buy 4 books; the first two were 25% off. Book 1 cost 13.00 and Book 2 cost 15.00. Book 3 & 4 were both $10.00 each. How much more money did Connor need to spend to receive free shipping?
[Answer]Book 1 was $12.50 and book 2 was $15.00 so 13.00 + 15.00 = $28.00. He was buying 4 books, so these 2 were 25% off so 28.00 * .25 = $7.00. These two books came out to 28 - 7 = $21.00. Books 3 & 4 were both $10 each so 2 * 10 = $20.00. When you add all 4 books together, 21 + 20 = $41.00. To get free shipping he would need to spend 50 - 41 = $9.00 more on books. The answer is 9.
