The price of a shoe was decreased by 22%. If the new price is $27.3….

Explanation

Let x = original price

A decrease of 22% = (100-22)% = 78% of the original price.

78% of x = 27.30

= \(\frac{78x}{100} = 27.30\)

78x = 2730

then, x = \(\frac{2730}{78}\)

x =  35

Therefore, the original price of the shoe was  $35.00.
