Management is considering the following independent courses of action in 2019 in order to maximize the return on investment for this division. (Based on original financial information above). Compute the controllable margin and the expected ROI for each proposed alternative. a) Reduce average operating assets by $125,000 with no change in controllable margin. b) Increase sales by $100,000 with no change in the contribution margin percentage (contribution margin ratio).

Total marketing effort is a term used to describe the critical decision factors that affect demand: price, advertising, distribution, and product quality. define the variable x to represent total marketing effort. a typical model that is used to predict demand as a function of total marketing effort is based on the power function: d = axb suppose that a is a positive number. different model forms result from varying the constant b. sketch the graphs of this model for b = 0, b = 1, 0< b< 1, b< 0, and b> 1. (we encourage you to use excel to do this.) what does each model tell you about the relationship between demand and marketing effort? what assumptions are implied? are they reasonable? how would you go about selecting the appropriate model?
