2) Chang saves up enough money to surprise his mom and buy her a new blouse for her birthday. The blouse costs about $70 and he uses a coupon for 20% off. How much does he save by using the coupon?

_________________________________

coupon for 20% off

20% = 0.2

The total of 100% of the price minus the discount =

100% - 20% = 80% or 1- 0.2 = 0.8

So then,

$70* 0.8 = $ 56 he pays

70 - 56 = 14 he saves

__________________________

Answer

He saves 14 by using the coupon

____________________

70*0.2= 14
