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?

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

so far i think you have the right thing going for you just remember soh cah toh

step-by-step explanation:

sine over hypotenuse

cosine   equals adjacent
