Acompany is considering the purchase of a new machine for $48,000. management predicts that the machine can produce sales of $16,000 each year for the next 10 years. expenses are expected to include direct materials, direct labor, and factory overhead totaling $8,000 per year plus depreciation of $4,000 per year. the company's after-tax net income, based on a tax rate of 40%, is $2,400. what is the approximate accounting rate of return for the machine?

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?
