Selected sales and operating data for three divisions of different structural engineering firms are given as follows: Required: 1. Compute the margin, turnover, and return on investment (ROI) for each division. 2. Compute the residual income (loss) for each division. 3. Assume that each division is presented with an investment opportunity that would yield a 15% rate of return. a. If performance is being measured by ROI, which division or divisions will probably accept the opportunity? b. If performance is being measured by residual income, which division or divisions will probably accept the opportunity? Compute the margin, turnover, and return on investment (ROI) for each division. Note: Do not round intermediate calculations. Round your answers to 1 decimal place. Compute the residual income for each division. Note: Loss amounts should be indicated by a minus sign.
