Question 5 • Applications and Modeling

Today's newspaper contains a 20%-off coupon at Old Army. The $100 jacket that you want was already reduced by 40%. What as the final price that you paid for the jacket?

Answer
A
$48
B
$46
C
$42
D
$40

Explanation

First, a 40% reduction on the $100 jacket leaves 60% of its price: $100 × 0.60 = $60. The 20%-off coupon then takes 20% off $60, so the final price is $60 × 0.80 = $48. The correct choice is $48.
