Answer:

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.
