You have been managing a $5 million portfolio that has a beta of 0.95 and a required rate of return of 11.175%. The current risk-free rate is 5%. Assume that you receive another $500,000. If you invest the money in a stock with a beta of 1.25, what will be the required return on your $5.5 million portfolio? Do not round intermediate calculations. Round your answer to two decimal places.
