Speedy Delivery Systems can buy a piece of equipment that should provide an 6 percent return and can be financed at 3 percent with debt. The CEO likes earning more than the cost of debt, and he thinks this would be a good deal. The firm can also buy a machine that would yield a 14 percent return but would cost 16 percent to finance through common equity. Earning less than the cost of equity sounds bad to the CEO. Assume debt and common equity each represent 50 percent of the firm's capital structure.
