The Nolan Corporation finds that it is necessary to determine its marginal cost of capital. Nolan's current capital structure calls for 30 percent debt, 20 percent preferred stock, and 50 percent common equity.

a. What is the initial weighted average cost of capital? (Include debt, preferred stock, and common equity in the form of retained earnings.)
