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?

Question

$8
$8.26
$9
$9.26

Answer 1

First, let's find the price of the CD after applying the coupon. The original price of the CD is $13.59, and Tony has a coupon for $1.85 off.

To find the price after the coupon:

\[ 13.59 - 1.85 = 11.74 \]

Now, we determine how much change Tony will receive after paying with a $20 bill:

\[ 20 - 11.74 = 8.26 \]

Now, we need to choose the best whole number estimate of the change:

The total change calculated is $8.26. The closest whole number to $8.26 is $8.

Therefore, the best whole number estimate of how much change Tony gets is:

\[ \boxed{8} \]
