I got C. 92.08
I'm not 100% sure I did this right, but I took the money gained between years nine and eleven and divided it by 2. I tried a few other ways, but none of my answers were choices.
Answer:
3080
Step-by-step explanation:
this is because after the decimal there is a 3 and when you round with a 3 the number stays the same.
The answer is x=20. You isolate the square root. Eliminate the radical on the left handside. And then solve it!
