A company is considering two designs for a machine in its manufacturing line. The first, called machine A, will cost $160000 in fixed costs and will cost $80 per unit in variable costs, for each unit it produces. The second, called B, will cost $270000 in fixed costs and will cost $2 per unit in variable costs, for each unit it produces. At what volume of production will the two machines cost the same

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?
