Answer:
Present value of the bonds 935.82
Step-by-step explanation:
We have to calculate the present value of the coupon interest service
and the face value redeem at maturity.

C = 1000 x 0.8 = 80
rate = 9%
time = 10

PV = 513.41262

Face Value = 1000
rate = 0.09

PV = 422.410807
Present value of the bonds
annuity PV + face PV = market price
513.41262 + 422.410807 = 935.823427 = 935.82 market value
