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%

tube or goog would be a great resource to with that question
