Can you please assist me with the below responsibility accounting problem?

The Broncos Corporation had net operating income of $400,000 and average operating assets of $2,000,000. The corporation requires a return on investment of 16%. How do you calculate the company's return on investment (ROI) and residual income (RI)?

Bronco Corporation is considering an investment of $100,000 in a project that will generate annual net operating income of $15,000. Would it be in the best interests of the company to make this investment? Why or why not?

Gean Corporation is considering an investment of $70,000 in a project that will generate annual net operating income of $14,000. If the division planning to make the investment currently has a return on investment of 20% and its manager is evaluated based on the division's ROI, will the division manager be inclined to request funds to make this investment?
