Barton Industries expects that its target capital structure for raising funds in the future for its capital budget will consist of $40\%$ debt, $5\%$ preferred stock, and $55\%$ common equity. Note that the firm's marginal tax rate is $40\%.$ Assume that the firm's cost of debt, rd$,$ is $8\mathrm{.}4\%,$ the firm's cost of preferred stock, rps$,$ is $7\mathrm{.}9\%$ and the firm's cost of equity is $12\mathrm{.}4\%$ for old equity, rs$,$ and $12\mathrm{.}93\%$ for new equity, re$.$ What is the firm's weighted average cost of capital $($WACC$1)$ if it uses retained earnings as its source of common equity? Round your answer to $3$ decimal places. Do not round intermediate calculations.

What is the firm$$s weighted average cost of capital $($WACC$2)$ if it has to issue new common stock? Round your answer to $3$ decimal places. Do not round intermediate calculations.
