Mitchell Manufacturing is considering the following capital projects. The internal rate of return (IRR) has been calculated for each project. Cost Project (Millions of dollars) $40 $40 $80 IRR 11.6% 11.2% 10.8% The optimal capital budget (OCB) is the budget size that maximizes the firm's wealth given the opportunities for investment and the cost of capital. Mitchell's managers have plotted the marginal cost of capital (MCC) schedule to reflect how the cost of capital increases as new capital is raised. Assume that the proposed projects are independent and equally risky and that their risks are equal to Mitchell's average existing assets.
