Answer:
The expected return on her portfolio is B) 11.8%
Explanation:
Hi, the expected return of a portfolio can be found by multiplying the weight of each of the assets times each of its expected return, that is:
[tex]E(portfolio)=E(Tbills)*Weight(Tbills)+E(other)*Weight(other)[/tex]
So everything should look like this
[tex]E(portfolio)=0.04*0.70+0.3*0.3=0.118[/tex]
The expected return of the portfolio is 11.8%, that is option B)
Best of luck.
