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?

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.

Thus, the answer is 9
