Suppose you are the money manager of a $$3\mathrm{.}74$ million investment fund. The fund consists of four stocks with the following investments and betas:

Stock Investment Beta

A $ $220,0001\mathrm{.}50$

B $500,000(0\mathrm{.}50)$

C $920,0001\mathrm{.}25$

D $2,100,0000\mathrm{.}75$

If the market's required rate of return is $12\%$ and the risk$-$free rate is $6\%,$ what is the fund's required rate of return? Do not round intermediate calculations. Round your answer to two decimal places.
