Answer:

Step-by-step explanation:

i think its 500%

but im not sure

because 20 divided by 4 = 5

and 5.0 = 500%

Answer:

 The percent change is 400%

Explanation:

We know that percentage change is given by the

[tex]\frac{change in value}{absolute value of the original value} \times 100[/tex]

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

[tex]\frac{-16}{4}[/tex] = -4

[tex]-4 \times[/tex] 100 = -400

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