Assume a person saves $62 a month by using coupons and doing comparison shopping. a. What is the amount of annual savings? b. What would be the future value of this annual amount over 10 years, assuming an interest rate of 4 percent? Use Exhibit 1-B. (Round FVA factor to 3 decimal places and final answer to 2 decimal places.)

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?
