Question

Mike had 280 dollars to spend on 8 books.After buying them he had 16 dollars. How much did each book cost?

Answer 1

280 subtract 16
264 divided by 8

Each book cost $33

Answer 2

Well, you can't really determine the price of 1 book, but you can find out the average cost.

280 - 16 = 8x (x = cost of 1 book)
264 = 8x
264/8 = 8x/8
33 = x

So the average cost of one book is 33$( A little expensive if I do say so myself)
Hope this helped!
