Answer:
the differene in the required rate of return of eahc company is 0.675%
Explanation:
we solve using the CAPM method:
[tex]Ke= r_f + \beta (r_m-r_f)[/tex]
risk free 0.0425
market rate 0.11
Company A
beta(non diversifiable risk) 0.7
[tex]Ke= 0.0425 + 0.7 (0.0675)[/tex]
Ke 0.08975 = 8.975%
Company B
beta(non diversifiable risk) 0.8
[tex]Ke= 0.0425 + 0.8 (0.0675)[/tex]
Ke 0.09650 = 9.65%
difference: 9.65% - 8.975% = 0.675%
