[4] How does the equation for valuing a bond change if semiannual payments are made? That is, if a $1000 face-value bond has 10% coupon rate, then this bond pays 2 coupon payments in each year and each coupon payment is $50 (= 10%*$1000/2).

(i) Find the value of a 10-year, semiannual payment, 10 percent coupon bond if nominal r_d = 10%.

(ii) Find the value of a 10-year, semiannual payment, 10 percent coupon bond if nominal r_d = 13%.

(iii) Find the value of a 10-year, semiannual payment, 10 percent coupon bond if nominal r_d = 7%.
