Tony buys cd that is priced at $13.59. ha has a coupon for $1.85 off. he pays with a $20 bill. which is the best whole number estimate of how much change he gets?

Tony will get $8.26 back.

Here's why:

First, let's take $1.85 away from $13.59, because he has a coupon. That leaves us with $11.74

Second, do $20 - $11.74 to get your answer, $8.26

answer: 42

use a calculator to find that 845/73 = 11.575

the whole part of the answer is 11. multiply this by 73 to get 11*73 = 803.

subtract that result from 845 to get 845 - 803 = 42
