Finance  Required Return from a Beta
posted by Dantes .
Hi, I need to learn how to explain and solve the following Finance problem.
I don't understand this at all!!!, please show all solutions...
Calculate the required return on an asset that has a beta of 1.25, when the expected return on the market portfolio is 10% and the riskless return is 6%

My bonds have a 12% coupon rate. Interest is paid semiannually. The bonds have a par vaule of $1000 and will mature 8 years from now. Compute the vaule of the bonds if the required rate of return is 8%?
