Answer:
ROI of investment center I = 17%
ROI of investment center II = 27%
ROI of investment center III = 34%
Step-by-step explanation:
Return on investment (ROI) can be calculated using the following formula:
ROI = Controllable margin / Average operating assets ……………………………… (1)
Using equation (1), we have:
ROI of investment center I = $848,640 / $4,992,000 = 0.17, or 17%
ROI of investment center II = $2,161,620 / $8,006,000 = 0.27, or 27%
ROI of investment center III = $4,103,120 / $12,068,000 = 0.34, or 34%
