Help, please and thank you

A 5-year Treasury bond has a 5.2% yield. A 10 -year Treasury bond yields 7.0%, and a 10 -year corporate bond yields 8.7%. The market expects that thnation will average 2.0% over the next 10 years (I10=2.0%). Assume that there is no maturity risk premium (MRP=0) and that the annual real risk-free rate, r, will remain constant over the next 10 years. (Hint: Remember that the default risk premium and the liquidity premlum are zero for Treasury securities: DRP=LP=0.) A 5 -year corporate bond has the same default risk premium and liquidity premium as the 10 -year corporate bond described. What is the yleld on this 5 -year corporate bond? Round your answer to one decimal place. %
