Question

Find the original price of a pair of shoes if the sale price is $63 after a 30% discount.

Answer 1

$90.00

Explanation:

First of all let x be the price of the pair of shoes that you are trying to find.

next since we have 30percent off that price we have

x - 0.30x = 0.70x

which in turn is equal to 63 dollars

so our expression is

0.70x = $63

x = 63 / 0.70

= $ 90.00

Answer 2

$90

Explanation:

To find the original price, divide 63 by 0.7:

63/0.7

= 90

So, the original price is $90
