Question

Ryan is cleaning out his room. his sister gives him 4 boxes of books to put with the 3 books he already had. when he finishes cleaning he discovers he now has 35 books on his shelves. how many books were in each box?

Answer 1

8 books per box.

Explanation:

One must assume that the books are evenly distributed among the boxes. Ryan has 3 books already and adds 4 boxes to reach a total of 35 books:

3 books + 4 boxes = 35 books

4 boxes = 35 books-3 books

4 boxes = 32 books

1 box = 8 books

There are 8 books per box.
