Sierra goes shopping and finds a jacket on sale for $120. the original price was $150. what was the percent change in the price of the jacket?
a. 80% discount
b. 30% discount
c. 20% discount
d. 50% discount

The sale price of the jacket that Sierra wants to buy = $120
Actual price of the jacket that Sierra wants to buy = $150
Amount of sale given on the jacket that Sierra wants to buy = (150 - 120) dollars
                                                                                                = 30 dollars
Percentage change in the price of jacket = (30/150) * 100
                                                                   = (1/5) * 100
                                                                   = 20 percent
So the percentage change in the price of the jacket that Sierra wanted to buy was 20%. The correct option among all the options given in the question is option "C".I hope that the procedure is clear enough for you to understand.
