You have been managing a $$5$ million portfolio that has a beta of $0\mathrm{.}85$ and a required rate of return of $7\mathrm{.}825\%.$ The current risk$-$free rate is $4\%.$ Assume that you receive another $$500,000.$ If you invest the money in a stock with a beta of $1\mathrm{.}15,$ what will be the required return on your $$5\mathrm{.}5$ million portfolio? Do not round intermediate calculations. Round your answer to two decimal places.
