Critical Thinking?

Question

Is the percent increase from 50 to 80 the same as the percent decrease from 80 to 50? Why or why not?

Answer 1

No. Because percent change is telling you something about "how much" things changed. So if you start with a larger number you are talking about a smaller percentage change. Your example

50 to 80 - change is 30 so 30/50 is a 60% change

80 to 50 - change is 30 so 30/80 is 37.5% change
