Answer:

He can buy 4 books with 2 dollars remaining

Step-by-step explanation:

30/7 = 4 R2

Answer: 4 books.

Explanation: First you divide $30 by 7, and you get 4 and 2/7 (2/7 as the remainder) left over. So you can't have 4 and 2/7 books, it has to be a whole number.

Therefore, he can buy 4 books. I hope this helped!
