Question

Dan had 175 dollars to spend on 6 books. After

buying them he had 13 dollars. How much did each book cost ?

Answer 1

27 dollars

Explanation:

On one side he had 175

One the other side he has 6 books and 13 dollars

175 = 6b+13

Subtract 13 from each side

175 -13 = 6b+13-13

162 = 6b

Divide each side by 6

162/6 = 6b/6

27 = b

Each book is 27 dollars
