Kent Enterprises issued $25-$year bonds $6$ years ago with a coupon rate of $6\mathrm{.}2\%.$ Currently, the bonds sell at a price of $$850.$

Are these bonds discount, par value, or premium bonds? $\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_$

Assuming semi$-$annual coupon payments, what is this bond's yield to maturity $($YTM$)?$

If the YTM were to increase by one percentage point, what would you expect to happen to the price of the bond?

One year later the YTM increases by $1\%,$ by what percentage would the price of the bond change as a result of this $1\%$ increase in the YTM$?$
