Answer:
-3
Step-by-step explanation:
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.
