Answer:
8
Step-by-step explanation:
The answer is 8 because the budget for the school is 200 and they bought 7 paper back books and paperback books cost 10$ each so we multiply 7 and 10 together and get 70 the we subtract 200 by 70 and get 130. Then we divide 130 by 15 and get 8.66666 and so we can by 8 books. Whith 10$ left over.
