Current Attempt in Progress

Four years ago, Maria Stills bought six$-$year, $5\mathrm{.}2$ percent coupon bonds issued by the Sheridan Corp. for $$950\mathrm{.}00.$ If she sells these bonds at the current price of $$897\mathrm{.}88,$ what will be her realized yield on the bonds? Assume similar coupon$-$paying bonds make annual coupon payments. Assume face value is $$1,000.($Round intermediate calculations to $5$ decimal places, e$.$g$.1\mathrm{.}25145$ and final answer to $2$ decimal places, e$.$g$.15\mathrm{.}25\%.)$

Realised rate of return $\%$
