Question

during a sale a dress is marked down for a selling price of $90 to a sale price of $81 what is the percent markdown​

Answer 1

10%

Explanation:

divide 90 into 81

so 81/90=.9

multiply that by 100 and you get 90 so 81 is 90% of 90 so it got marked down 10%

Answer 2

This is a 10% markdown.

$90-$81=$9
And 9/90=10%

Check: 10% of 90 is 9.
90-9=81
