Question

How do you calculate the percent change of 200 to 158?

Answer 1

Decrease of `21%`

Explanation:

The change is obviously a decrease, but we use the same method for an increase and a decrease.

Calculate the actual change (bigger value - smaller value)

`200-158 = 42`

To calculate the `%` change : `" " color(blue)("change"/"original" xx 100%)`

`42/200 xx 100%`

`= 21%`decrease of `21%`
