Answer:

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

Step-by-step 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 = [tex]\frac{45}{100}[/tex] × x

or, 45 × x = 40.50 × 100

Or, 45 × x = [tex]\frac{4050}{100}[/tex] × 100

or, 45 × x = 4050

∴  x = [tex]\frac{4050}{45}[/tex]

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
