Peta has 4 friends now. last year she had 12. what is the percent of change?

we simply see 4 has multiplied by - 3

-12 = 4 x - 3

This becomes - 300%

We then add the 100 = initial amount onto a negatove percentage = - 300 + 100 = - 200% change.

Step-by-step explanation:

3.00 x 4 = 12

4 + 8 = 12

4 x - 2.00 = - 8 being the change. The answer is - 2.00 = - 200%

Shows part of the answer and proves the answer is - 200%
