Answer 1

In order for every book to be the same price they would have to be $9. But his cost 13. So I would subtract. 27-13=14. So he has $14 left. He still has to buy 2 more books so each of his sisters have a book. So he would have $7 to spend on each of them. Your answer would be yes he can spend $5 on each additional book.
