Assume that you are going to invest $120,000 in a two asset portfolio. You will invest $80,000 in the fully diversified market portfolio and the remainder of your funds will be invested in the riskless security. Assume the market risk premium is 8% and the riskless return is 4%. Compute the expected return on this portfolio.

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?
