During a​ sale, a dress is marked down from a selling price of ​$80 to a sale price of ​$72. What is the percent​ markdown?

Answer 1

First, find the dollar amount of the discount.

$80-$72 = $8. There is an $8 discount.

Next, we want to know what percentage of $80 is $8.(Part/whole)

8/80 (think: 8 is what percent of 80?)

= 0.10

= 10% discount
