Tony buys a CD that is priced at $13.59. He 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?

Respuesta :

13.59 - 1.85 = 11.74

20.00 - 11.74 = 8.26

So the best whole number of change is 8.
Estimate
$13.59 = $14
$1.85 = $2

$14 - $2 = $12
$20 - $12 =$8

answer
he gets $8 change
