(a) The before-tax cost of debt is less than the before-tax cost of equity. Therefore debt is a cheaper form of financing than equity so companies should try to finance their projects with debt only.

(b) Debt makes a firm's equity more risky. Therefore the higher the amount of debt, the higher the cost of equity.

(c) The more debt a firm has, the higher its tax shields. Therefore firms should seek to have as much debt and as little equity as possible.

(d) The more debt, the lower the firm's after tax WACC. The after tax WACC is the discount rate that discounts the firm's cash flows, so the lower it is the more the firm is worth. Therefore firms should try to make their after tax WACC as low as possible by using as much debt as possible.

(e) The less debt, the lower the chance of bankruptcy. Therefore firms should try to pay off all of their debt so that they are financed by equity only.

(a) The project should be rejected.

(b) The project's IRR is more than its required return.

(c) The project's IRR is less than its required return.

(d) The project's IRR is equal to its required return.

(e) The project will never pay itself off, assuming that the discount rate is positive.

(a) If a project has a positive NPV, its Profitability Index (PI) will be more than 1.

(b) If a project has a negative NPV and the discount rate is zero, then the payback period will be infinite so the project will never pay back its costs.

(c) If a project's NPV is zero, then the PI must be 1.

(d) If a project has a negative NPV, its IRR will be negative.

(e) If a project has a positive NPV, its Average Accounting Return (AAR) is not necessarily positive, it could be positive, negative or zero.

(a) WACC before tax ##= r_D.\dfrac{D}{V_L} + r_{EL}.\dfrac{E_L}{V_L}##

(b) WACC before tax ##= r_f + \beta_{VL}.(r_m - r_f)##

(c) WACC after tax ##= r_D.(1-t_c).\dfrac{D}{V_L} + r_{EL}.\dfrac{E_L}{V_L}##

(d) WACC after tax ##= r_f + \beta_{VL}.(r_m - r_f) - \dfrac{r_D.D.t_c}{V_L}##

(e) WACC after tax ##= r_f + \beta_{VL}.(r_m - r_f)##
