Question

If Eli showed a 8.9% ROI on his $8000.00 investment, how much was his return on his investment

Answer 1

8.9% is equal to 0.089 because a percent is over a 100. So, you can just multiply the ROI by the investment to get:

$0.089(8000) = 712$

Your answer is: $712.

Answer 2

$8,000.00 represents 100%

          $ ? represents 8.9 %

cross multiply ?=8.9·8,000/100=712

answer is $712 ROI
