Question

Chester has a coupon for  off the price of a shirt. If the shirt originally costs $25.30, what discount would Chester receive from using his coupon?

Answer 1

1/5 off is a 20% discount

25.3 - .2(25.3)

=(1-.2)(25.3)

= .8(25.3)

= $20.24 = discounted price

with discount of $5.06

$25.30 - $5.06 = $20.24
