You have $128,000 to invest in a portfolio containing Stock X, Stock Y, and a risk-free asset. You must invest all of your money. Your goal is to create a portfolio that has an expected return of 23 percent and that has only 78 percent of the risk of the overall market. If X has an expected return of 36 percent and a beta of 1.3, Y has an expected return of 21.5 percent and a beta of 1.8, and the risk-free rate is 6.4 percent, how much money will you invest in Stock Y? (Round your answer to 2 decimal places. Omit the "$" sign in your response.)
