What is the return on the market portfolio $($rM$),$ when the risk$-$free rate $($rRF$)$ is $1\mathrm{.}6\%$ and the market is in equilibrium and if a stock has a beta of $1\mathrm{.}0$ and a required rate of return of $12\mathrm{.}8\%?$

Show your answer to the nearest $\mathrm{.}1\%$ using whole numbers $($e$.$g$.,$ enter $14\mathrm{.}1\%$ as $14\mathrm{.}1$ rather than $\mathrm{.}141).$
