Percentage Problem 6

The price of an item changed from $120 to $100. Then later the price decreased again from $100 to $80. Which of the two decreases was larger in percentage term?

Expert Solution

First decrease in percent

part / whole = (120 - 100) / 120 = 0.17 = 17%

Second decrease in percent

part / whole = (100 - 80) / 100 = 0.20 = 20%

The second decrease was larger in percent term. The part were the same in both cases but the whole was smaller in the second decrease.
