The cost of capital of a company that uses 45 percent debt that has an after-tax cost of debt of 10 percent and 55 percent equity that has a cost of 15 percent is:.

12.75 %

Explanation:

Cost of Capital is calculated on a Weighted Average basis. This is because there is a Pooling of Funds when it comes to financing projects. So Cost of Capital is the Return that is Required by providers of Long Term source of finance.

Cost of Capital = E/V × Ke + D/V × Kd

Where,

E/V = Market Weight of Equity

      = 0.55

Ke = Cost of Equity

    = 15%

D/E = Market Weight of Debt

      = 0.45

Kd = Cost of Debt

     = 10%

Therefore,

Cost of Capital = 0.55 × 15% +  0.45 × 10%

                         = 12.75 %

both are integral parts of a corporate balance sheet. the cash flow statement, or statement of cash flows, measures the sources of a company's cash and its uses of cash over a specific time period. the income statement measures a company's financial performance, such as revenues, expenses, profits or losses over a specific time period (in fact, it's sometimes called a statement of financial performance).

a cash flow statement shows exactly how much money a company has received and how much it has spent, traditionally over a period of one month. it captures the current operating results and changes on the balance sheet, such as increases or decreases in accounts receivable or accounts payable, and does not include noncash accounting items such as depreciation and amortization. the cash flow generally comes from revenue received as a result of business activity, but it may be augmented by funds available as a result of credit. a cash flow statement is used to determine the short-term viability and liquidity of a company, specifically how well it is positioned to pay its bills and vendors.
