Question

What is the percent of decrease? initial value:50 Final value:40

Answer 1

20% decrease

Explanation:

Your equation is;

`Percent drop = 100times[(IV)-(FV)]/ (IV)`

IV stands for the initial value
FV stands for the final value

When you apply this formula:

`Decrease = 100times(50-40)/50`

`Decrease= 100times1/5 = 20%`

It means the decrease is 20%.
