Answer 1

Step-by-step explanation:

i think its 500%

but im not sure

because 20 divided by 4 = 5

and 5.0 = 500%

Answer 2

The percent change is 400%

Step-by-step explanation:

We know that percentage change is given by the

`(change in value)/(absolute value of the original value) * 100`

i.e we find the difference between the original value and current value and then divide it by original value and multiply the obtained value with 100.

a negative percentage change indicates increase in value.

so we get 4 - 20 = -16

`(-16)/(4)` = -4

`-4 *` 100 = -400

hence there is an increase of 400% in the percentage which is the required percentage.
