You manage a risky portfolio with an expected rate of return of 22% and a standard deviation of 34%. The T-bill rate is 6%. Your risky portfolio includes the following investments in the given proportions:

Stock A	31	%
Stock B	36	%
Stock C	33	%

Suppose that your client decides to invest in your portfolio a proportion y of the total investment budget so that the overall portfolio will have an expected rate of return of 18%. a. What is the proportion y? (Round your answer to the nearest whole number.) Y= b. What are your clients investment proportions in your three stocks and the T-bill fund?
