The cost of capital from this bond debt is? (Round to two decimal places.)

b. Common stock for a firm that paid a $1.03 dividend last year. The dividends are expected to grow at a rate of 15% per year into the foreseeable future. The price of this stock is now $2539.

The cost of capital from the common equity is? (Round to two decimal places.)

c. A bond that has a $1,000 par value and a coupon interest rate of 114%. A new issue would sell for $1,154 per bond and mature in 20 years. The firm's tax rate is 34%.

The cost of capital from this bond debt is? (Round to two decimal places.)

d. A preferred stock paying a 7.4% dividend on a $107 par value. If a new issue is offered, the shares would sell for $84.28 per share.

The cost of the preferred stock is? (Round to two decimal places.)
