解析：
The marginal cost of capital (MCC) is defined as the weighted average cost of the last dollar raised by the company. Typically, the marginal cost of capital will increase as more capital is raised by the firm. The marginal cost of capital is the weighted average rate across all sources of long-term financings - bonds, preferred stock, and common stock - when the final dollar was obtained, regardless of its specific source.
