Question

Helping my daughter with ratio table homework. I do not understand the concept of the tables. Here is one of her questions that she has to answer in a table.
A book store bought 160 copies of a book from the publisher for $4000. If the store gives away 2 books, how much money will it lose?

Answer 1

First you divide $4000 by 160 to see how much each book costs. Then you multiply 2 times the cost for each book and subtract that from $4000.

$4000/160= $25
$25=1 book
So if the store gives away 2 books that's $50 dollars. $4000-$50 equals 3,950
