Last year Janet purchased a $\backslash (\backslash$$ $1,000\backslash )$ face value corporate bond with a $\backslash (7\backslash \%\backslash )$ annual coupon rate and a $15-$year maturity. At the time of the purchase, it had an expected yield to maturity of $\backslash (7\mathrm{.}62\backslash \%\backslash ).$ If Janet sold the bond today for $\backslash (\backslash$$ $1,124\mathrm{.}66\backslash ),$ what rate of return would she have earned for the past year? Do not round intermediate calculations. Round your answer to two decimal places.
