Step-by-step explanation:
1. Calculation to determine the ROI
Using this formula
ROI= Net income/Average operating assets
Let plug in the formula
ROI= $70,000 / $350,000*100
ROI= 20%
2) ROI = ($70,000 +$18,200)/$350000"100
ROI=$88,200/$350,000*100
ROI=25.2%
3) ROI = ($70,000 +$14,000)/350000*100
ROI=$84,000/$350,000*100
ROI=24%
