Question

A book has a list price of $39.99, but the bookstore receives a 40% discount from the publisher. How much does the bookstore have to pay per copy of this book?

Answer 1

Hard to believe this is college level but here we go! You're finding what the price is of a book that is $39.99 at a 40% discount. In order to find the answer you multiply your price times the discount in decimal form. Then subtract this value from the original.

40% ⇒ .40 (Note: Percentages are out of 100)

[39.99 x .40] = 15.996

[39.99 - 15.996] = 23.994 

The bookstore pays $23.99 per copy.
