The cost of debt, rd, is normally less than rs, so rd(1 - T) will normally be much less than rs. Therefore, as long as the firm is not completely debt financed, the weighted average cost of capital (WACC) will normally be greater than rd(1 - T) [ T / F ]. The discounted payback will always be longer than the payback if the applicable discount rate is greater than zero. [ T / F ]. a. True, True b. True, False c. False, True d. False, False
