Explanation:

Residual Income is measure of how much a division or a part of a business is able to generate over and above the company-wide opportunity cost of capital.

A division with a  controllable margin  over and above the cost of fund is evaluated to be profitable .

Residual income = Controllable margin - (cost of capital(%)× operating assets)

                      = 900,460  - (19%× 4,093,000)

                        =  $ 122,790.00

Return on Investment is the proportion of operating assets that earned as controllable margin by the division.

ROI = Contribution margin / Operating assets ×  100

ROI = 900460/ 4,093,000 × 100

   =    22%
