Question

Mike had 228 dollars to spend on 7 books. After

buying them he had 18 dollars. How much did each book cost ?

Answer 1

$30

Explanation:

Total amount Mike had = $228

Amount remaining = $ 18

Amount spent on books = 228 - 18 = $210

Cost of wach book = 210/7 = $30

Cost of each book is 30 dollars.

Answer 2

$30

Explanation:

We know that the cost of all of the books was 228 - 18 = 210 dollars because Mike had 18 dollars left over. Assuming that each book cost the same amount, we know that each book costs 210 / 7 = $30.
