2. (10%) Station WJXT is considering the replacement of its old fully depreciated sound mixer. Two new models are available. Mixer X has a cost of $345,000, a 15-year life, and after-tax cash flows (including the tax shield from depreciation) of $70,000 per year. Mixer Y has a cost of $130,000, a 5-year expected life, and after-tax cash flows (including the tax shield from depreciation) of $60,000 per year. No new technological developments are expected. The discount rate is 12 percent. Should WJXT replace the old mixer, and, if so, with X or Y? (Hint: If WJXT chooses mixer Y, it can always buy a one when the old one is out of use after its economic life. Since there are no technological developments, the new mixer Y will generate the same cashflow)
