41) You have been asked to evaluate two pollution control devices. The wet scrub costs $100 to set up and $50 per year to operate. It must be completely replaced every 3 years, and it has no salvage value. The dry scrub device costs $200 to set up and $30 per year to operate. It lasts for 5 years and has no salvage value. Assuming pollution control equipment is replaced as it wears out, which method do you recommend if the cost of capital is 10%? Determine the equivalent annuity cost (EAC) and show your decision by marking your choice. All revenues are assumed to be the same.

10.33 The risk-free rate is 7.6 percent. Potpourri Inc. stock has a beta of 1.7 and an expected return of 16.7 percent. Assume the capital-asset-pricing model holds.

1. What is the expected market risk premium?

Using the CAPM equation

Expected return = Rf + (Rm-Rf) X beta

Where (Rm-Rf) is the market risk premium

16.7% = 7.6% + (Rm-Rf) X 1.7

(Rm-Rf) = (16.7%-7.6%)/1.7 = 5.35%

2. Magnolia Industries stock has a beta of 0.8. What is the expected return on the Magnolia stock?

Using the CAPM equation with market risk premium = 5.35%

Expected return = 7.6% + 5.35%X0.8

= 11.88%

3. Suppose you have invested $10,000 in a combination of Potpourri and Magnolia stock. The beta of the portfolio is 1.07. How much did you invest in each stock? What is the expected return of the portfolio?

The beta of a portfolio is the weighted average beta of individual stocks. Let A% be invested in Potpourri, then (100-A%) would be invested in Magnolia. The weighted average beta is

Portfolio beta = Proportion of Potpourri X beta of potpourri + Proportion of Magnolia X beta of magnolia

1.07 = A% X 1.7 + (100-A%) X 0.8

This gives A as 30%, so investment in Potpourri is 10,000X30%=$3,000 and the investment in Magnolia will be $7,000

Expected return = 0.3X16.7% + 0.7 X 11.88% = 13.33%

39) The Tuft Company is generating cash flow of $333,000 per year. If ...
