As the statement says that the price of the jacket was reduced by 40%, to determine the percent that the sale price represents from the original price, you have to subtract 40% from 100% that represents the original price:
100%-40%= 60%
This means that $30 represents 60% of the original price.
-To determine the original price of the jacket, you can use the rule of three:
$30 → 60%
x ← 100%
x=(100*30)/60= 50
According to this, the original price of a jacket was $50.
