The answers are provided, I need to know how to find K_e using the Capital Asset Pricing Model formula in 3 different ways. Thank you

1. K_e = R_f + Beta (K_m + R_f)

2. K_e = R_f + Beta (R_f + Premium - R_f) , where K_m = (R_f + Premium)

3. K_e = R_f + Beta (Premium)

The Capital Asset Pricing Model (CAPM), calculates the required rate of return of a risky asset (a stock). Given the following information, calculate Ke
