A)

An individual has $40,000 invested in a stock with a beta of 0.7 and another $80,000 invested in a stock with a beta of 2.3. 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.

B)

Assume that the risk-free rate is 5.5% and the required return on the market is 12%. What is the required rate of return on a stock with a beta of 2? Round your answer to two decimal places.

C) Stock R has a beta of 2.0, Stock S has a beta of 0.65, the required return on an average stock is 10%, and the risk-free rate of return is 3%. By how much does the required return on the riskier stock exceed the required return on the less risky stock? Round your answer to two decimal places.
