Suppose the expected returns and standard deviations of Stocks A and B are E(R_A) = .097, E(R_B) = .157, sigma_A = 367, and sigma_B = 627

Calculate the expected return of a portfolio that is composed of 42 percent Stock A and 58 percent Stock B when the correlation between the returns on A and B is .57.

(Do not round intermediate calculations and enter your answer as a percent rounded to 2 decimal places, e.g., 32.16.)
