current market conditions are such that the risk-free rate is 2%, the market risk premium is 10% and Firm A's Beta is 1.25,

required return = risk free rate + (beta * market risk premium)

required return = 2% + (1.25 * 10%) = 14.50%

If Firm B is less volatile than the market, and has a Beta of 0.5, what would be its required return in the same market conditions as listed above?
