Suppose a two$-$year coupon bond has annual coupon payments of $$40(5\%$ coupon rate$)$ and a face value of $$800.$ The interest rate is $8\%.$ Compute the present value of the coupon payments $($PCP$)$ and the principal payment of the bond $($PBP$).$ What is the price of this bond $($P$)?$ If the maturity of the bond increases to $3$ years with one more coupon payment of $$40$ and the principal payment at the end of third year, how will the bond price change?
