An individual has $$35,000$ invested in a stock with a beta of $0\mathrm{.}4$ and another $$65,000$ invested in a stock with a beta of $1\mathrm{.}1.$ If these are the only two investments in her portfolio, what is her portfolio's beta? Do not round intermediate calculations. Round your answer to two decimal places.

Assume that the risk$-$free rate is $4\mathrm{.}5\%$ and the required return on the market is $11\%.$ What is the required rate of return on a stock with a beta of $3?$ Round your answer to two decimal places.

Suppose you are the money manager of a $$4\mathrm{.}08$ million investment fund. The fund consists of four stocks with the following investments and betas:

Stock Investment Beta

A $ $340,0001\mathrm{.}50$

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

C $1,140,0001\mathrm{.}25$

D $2,000,0000\mathrm{.}75$

If the market's required rate of return is $12\%$ and the risk$-$free rate is $5\%,$ what is the fund's required rate of return? Do not round intermediate calculations. Round your answer to two decimal places.
