Question

Janet is buying a $28 necklace. The store reduces the price by 20% and then applies a $2 off coupon. How much will Janet pay for the necklace?

Answer 1

Answer:

To compute how much Janet will pay we need to reduce the original $28 price by 20% of that price, which is the same as 0.2 times that price, which we would compute as:

$28 - 0.2 ($28)

$28 -$5.60

We then apply the $2 coupon:

$28 - $5.60 - $2

$28 -$7.60 = $20.40
