Suppose you are the money manager of a $$4\mathrm{.}54$ million investment fund. The fund consists of four stocks with the following investments and betas:

Stock Investment Beta

A $ $420,0001\mathrm{.}50$

B $600,000(0\mathrm{.}50)$

C $1,320,0001\mathrm{.}25$

D $2,200,0000\mathrm{.}75$

If the market's required rate of return is $9\%$ and the risk$-$free rate is $4\%,$ what is the fund's required rate of return? Do not round intermediate calculations. Round your answer to two decimal places.
