Answer:
Cost of the bonds = 4600 $
Total annual interest = 350 $
Yield = 7.6 %
Explanation:
Fred purchased the bonds for 1000 $ at 92. 1000 $ is the face value of the bond. That means the actual value of the bond = 92 % of 1000.
⇒ Actual value of the bond =

= 920 $
Since, Fred purchased five bonds, the total cost of the bonds = 920 X 5
= 4600 $
Actual cost of the bond = 4600 $
Total interest on the bond = Rate on the bond X Face value of the bond
=
= 70 $
Interest on all the 5 bonds = 70 X 5 = 350 $
Total interest on the bond = 350 $
Yield is the amount got as returns on the bond.
We have the following formula to calculate yield.
Yield =

∴ Yield =

Therefore, Yield = 7.6%
