Question

Kim bought a pair of shoes on sale for $40.50. The sale price was 45% of the original price. What was the original price of the shoes?

Answer 1

The original price of the pairs of shoes which Kim bought is $ 90

Explanation:

Given as :

The selling price of a pair of shoes = s.p = $ 40.50

The selling price = 45 % of the original price of shoes

Let The original price of the shoes = x

Now, According to question

∵ The selling price = 45 % of the original price of shoes

∴ s.p = 45 % × x

or, $ 40.50 = 45 % × x

or, $ 40.50 =
`(45)/(100)` × x

or, 45 × x = 40.50 × 100

Or, 45 × x =
`(4050)/(100)` × 100

or, 45 × x = 4050

∴ x =
`(4050)/(45)`

I.e x = $ 90

So, original price of shoes = x = $ 90

Hence The original price of the pairs of shoes which Kim bought is $ 90 Answer
