Should operating income or net income be used to determine the rate of return (ROI) for the Rite investment center? Explain your answer.

Should operating assets or total assets be used to determine the ROI for the Rite investment center? Explain your answer.

Calculate the ROI for Rite. Round computation to 1 decimal point.

Gwinnett has a desired ROI of 8 percent. Headquarters has $300,000 of funds to assign to its investment centers. The manager of the Rite Division has an opportunity to invest the funds at an ROI of 9 percent. The other two divisions have investment opportunities that yield only 6.5 percent. Even so, the manager of Rite rejects the additional funding. Explain why the manager of Rite would reject the funds under these circumstances. Round the computation to one decimal point.

Explain how residual income could be used to encourage the manager to accept the additional funds.
