Answer:
-19.999999999999996
Explanation:
The percentage change differs from percent increase and percent decrease in the sense that we can see both directions of the change. For example, the percent increase calculator calculates the amount of increase, in which we would say, "x percent increase". The percent decrease calculator calculates the amount of decrease, in which we would say, "x percent decrease". The percent change calculator would yield a result in which we would say, "x percent increase or decrease". To calculate percent change we need to take the difference between the starting value and ending value, divide by the starting value and multiply the result by 100. Then take the absolute value. The section below will go into more detail and show how to solve a problem.
