Final answer:
Osaka's ROI is 24% with a residual income of $253,000, while Yokohama's ROI is 16% with a residual income of $330,000.
Step-by-step explanation:
To compute the Return on Investment (ROI) for each division, we use the formula:
ROI = (Net Operating Income / Average Operating Assets) * 100
For Division Osaka:
ROI = ($552,000 / $2,300,000) * 100 = 24%
For Division Yokohama:
ROI = ($1,760,000 / $11,000,000) * 100 = 16%
The Residual Income (RI) is calculated by subtracting the product of the minimum required rate of return (13%) and the average operating assets from the net operating income.
For Division Osaka:
RI = $552,000 - (0.13 * $2,300,000) = $552,000 - $299,000 = $253,000
For Division Yokohama:
RI = $1,760,000 - (0.13 * $11,000,000) = $1,760,000 - $1,430,000 = $330,000
