Answer:
β = 1.45
Explanation:
The beta of the portfolio is defined as an average of the betas (β) of each asset within the portfolio weighted by their respective invested amounts (A):
[tex]A_{P}* \beta_{P} =A_{B}* \beta_{B} +A_{D}* \beta_{D} +A_{F}* \beta_{F} \\\beta_{P} =\frac{20,000 * 1.5 + 50,000*2.0 +30,000*0.5}{100,000}\\\beta_{P} = 1.45[/tex]
The beta of the portfolio is 1.45
