Suppose you bought a five$-$year zero$-$coupon Treasury bond for $$800$ per $$1000$ face value. What is the yield to maturity $($annual compounding$)$ on the bond? I am not sure how you are coming up with $4\mathrm{.}56\%$; I am coming up with something different I have tried several different ways to get the answer but I am coming up with $0\mathrm{.}6078$ or $0\mathrm{.}75??$
