$($Calculating the weighted average cost of capital$)$ You are working as a consultant to the Lulu Athletic Clothing Company, and you have been asked to compute the appropriate discount rate to use in the evaluation of the purchase of a new warehouse facility. You have determined the market value of the firm's current capital structure $($which the firm considers to be its target mix of financing sources$)$ as follows: To finance the purchase, Lulu will sell $20-$year bonds with a $$1,000$ par value paying $5\mathrm{.}5$ percent per year $($with interest paid semiannually$)$ at the market price of $$1,025.$ Preferred stock paying a $$2\mathrm{.}44$ dividend can be sold for $$34\mathrm{.}84.$ Common stock for Lulu is currently selling for $$49\mathrm{.}13$ per share. The firm paid a $$4\mathrm{.}06$ dividend last year and expects dividends to continue growing at a rate of $4\mathrm{.}2$ percent per year for the indefinite future. The firm's maginal tax rate is $34$ percent. What discount rate should you use to evaluate the warehouse project?
