Answer:
The expected return on her portfolio is B) 11.8%
Step-by-step 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:
![E(portfolio)=E(Tbills)*Weight(Tbills)+E(other)*Weight(other)](https://img.qammunity.org/2020/formulas/business/college/2yhr9oe9nscu767nm9z1dv7zt87k582xxt.png)
So everything should look like this
![E(portfolio)=0.04*0.70+0.3*0.3=0.118](https://img.qammunity.org/2020/formulas/business/college/ocyfa2iu8qp558kka9eldv79ynwcqltyco.png)
The expected return of the portfolio is 11.8%, that is option B)
Best of luck.
