#### Solution Preview

Here are the terms and the formula for calculating the expected return:

Terms

Required Rate: Ke

Risk Free Rate: Rf

b: Beta Coefficient

Km: Expected Return

Formula

Ke=Rf + b(Km-Rf)

Solve as follows:

Trying to solve for Ke, Rf is given as 6%, b is given as 0.7, Km is given as 13%

Ke=Rf + b(Km-Rf)

Ke=6% + 0.7(13%-6%)

Ke=6% + 0.7(7%)

Ke=6% + 4.9%

Ke=10.9%

The required rate is 10.9%

Here's an explanation of why:

Basically, we are trying to figure your required rate of return on a stock with relatively low volatility ...

#### Solution Summary

The solution is a calculation of the required rate of return on a stock with given rates including risk free, market, and beta.
