Question: A book has a price of $39.99 but receives a 40% discount from the publisher. How much does the bookstore have to pay per copy?
There are a couple ways to do this. I'll show you both.
Multiply $39.99 by .40 (which is achieved by taking out the percentage and dividing by 100)
\(39.99*.40=16\)
Subtract $39.99 by $16 which is $23.99
Other but much quicker way is to multiply $39.99 by 60%
\(39.99*16\) = \($23.99\)
Answer: $23.99
