A firm is considering a new project that will require an initial investment of $10 million. The project is expected to generate cash flows of $3 million per year for the next 10 years. The firm has determined that the appropriate discount rate for this project is the weighted average cost of capital (WACC), which is currently 10%. The firm's capital structure consists of 40% debt and 60% equity. The before-tax cost of debt is 7%, and the firm's marginal tax rate is 35%. a. What is the firm's WACC? b. What is the net present value (NPV) of the proposed project? c. Should the firm proceed with the project, based on its NPV? Explain your reasoning.
