A firm is considering a project. The firm has enough retained earnings to fund the common stockholders' share of the financing, so we'll use Weighted Average Cost of Capital One to determine the firm's cost of capital for this project:

WACC$1=$ Wd $*$ After$-$tax Cost of Debt $+$ Wps $*$ Cost of Preferred Stock $+$ Wcse $*$ Cost of Retained Earnings

$0\mathrm{.}25*5\mathrm{.}11\%+0\mathrm{.}35*8\mathrm{.}76\%+0\mathrm{.}4*11\mathrm{.}68\%=$ WACC$1$

The proposed project's expected cash flows are as follows:

Year Cash Flow

$0$ $ $(75,000\mathrm{.}00)$

$1$ $ $15,468\mathrm{.}00$

$2$ $ $17,859\mathrm{.}00$

$3$ $ $19,527\mathrm{.}00$

$4$ $ $21,252\mathrm{.}00$

$5$ $ $26,525\mathrm{.}00$

The estimated return for common stockholders on their retained earnings is $\_\_\_\_\_.$

Note: Put your answer in percentage terms, but do not include the percent sign, and be sure to go out two decimal places $($e$.$g$.$ enter $12\mathrm{.}34$ for $12\mathrm{.}34\%)$
