Compute the weighted cost of capital for a firm with a marginal tax rate of $34\%,$ a capital structure of $43\%$ common stock, $15\%$ preferred stock and the remainder in debt given the following:

A bond with a coupon rate of $11\%$ with interest payments of $$55\mathrm{.}00$ paid semiannually. The bonds have a current market value of $$1,125$ and will mature in $10$ years. What is the after$-$tax cost of debt? $(5$ points$)$

A new common stock issue that will pay $$1\mathrm{.}93$ next year. The dividends are expected to continue to grow at $7\mathrm{.}0\%$ per year forever. The current price of the common stock is $$27\mathrm{.}50.$ What is the cost of common equity? $(5$ points$)$

A preferred stock that sells for $$125$ and pays a dividend of $9\%$ and has a par value of $$100.$ What is the cost of preferred stock? $(5$ points$)$

What is the weighted average cost of capital for the firm? $(8$ points$)$
