Keith had 331 dollars to spend on 9 books . after buying them he had 16 dollars . how much did each book cost ?

First, let’s figure out how much of his money he spent on the total amount of books.

We’ll take his staring amount ($331) and subtract it by how much money he had left over ($16)

$331 - $16 = $315

So now we know that he spent $315 for ALL the books.

Now, we divide $315 by how many books he purchased (9) to find out how much he paid for EACH book

$315 ÷ 9 = $35

Therefore, EACH book costs $35

Hope this helps you
