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?

Answer 1

estimate : 14 - 2 = 12......20 - 12 = 8

real thing :
13.59 - 1.85 = 11.74
20 - 11.74 = 8.26

Answer 2

Best whole number estimate of change Tony gets is equals to $8.

As per the condition given  we have,

Price of CD Tony needs to pay
