Question

Karen wants to buy a $22.50 jacket that is marked 20% off. Select from the drop-down menu to correctly complete the sentence. The best estimate for the discount can be found using the expression

Answer 1

`\$22.50*0.20=\$4.50`

Explanation:

Let

x-------> original price

y------> percentage of discount

z-----> discount

we know that

`z=xy`

In this problem we have

`x=\$22.50`

`y=20\%=(20)/(100)=0.20`

Substitute the values

`z=\$22.50*0.20=\$4.50`

Answer 2

discount = price times % off

discount = 22.50 x 0.20

discount = $4.50
