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