Answer:
1. PV = 101.87
2. YTM = 7.46%
3. Price of the bond  is $100.92
Explanation:
PV = 8.5/ (1.065) + 108.5/ (1.075)2
PV = 7.981 + 93.889
PV = 101.87
Part B:
PV = 101.870
FV = 100
N = 2
PMT = 8.5
Using Financial Calculator:
r = 7.459237
YTM = 7.46%
Part C:
The forward rate for next year, derived from the zero-coupon yield curve, is approximately:
(1 + forward Rate) = (1 + 0.075)2/ (1.065)
forward rate = 8.51%
Price of the bond = 108.5/ (1.0851)
Price of the bond = 100
Part D:
Interest Rate = 8.51% - 1% = 7.51%
Price of the bond = 108.5/ (1.0751)
Price of the bond = 100.92
