You have $100,000 to invest in either Stock D, Stock F, or a risk-free asset. You must invest all of your money. Your goal is to create a portfolio that has an expected return of 10.9 percent. If D has an expected return of 12.8 percent, F has an expected return of 9.7 percent, the risk-free rate is 3.5 percent, and you invest $50,000 in Stock D, how much will you invest in Stock F? Note: Do not round intermediate calculations and round your answer to 2 decimal places, e.g., 32.16.
