Selected sales and operating data for three divisions of different structural engineering firms aregiven as follows: division a division b division c sales $ 6,000,000 $ 10,000,000 $ 9,100,000 average operating assets $ 1,200,000 $ 2,500,000 $ 1,820,000 net operating income $ 306,000 $ 910,000 $ 213,850 minimum required rate of return 20.00 % 36.40 % 17.00 %required: 1. compute the return on investment (roi) for each division using the formula stated in terms of margin and turnover. (round your turnover answers to 2 decimal places. round your margin and roi percentage answers to 2 decimal places (i. e., 0.1234 should be entered as 12. 2. compute the residual income (loss) for each division. (loss amounts should be indicated by a minus sign. round your required rate of return percentage answers to 2 decimal places (i. e., 0.1234 should be entered as 12. 3. assume that each division is presented with an investment opportunity that would yield a 22% rate of return. a. if performance is being measured by roi, which division or divisions will probably accept or reject the opportunity? b. if performance is being measured by residual income, which division or divisions will probably accept or reject the opportunity?
