Answer: 40%
Step-by-step explanation:
From the question, we are informed that TrunkLine Company debtholders are promised payments of $35 if the firm does well, but will receive only $20 if the firm does poorly.
When the bonds are selling at a price of $25, the promised return to the bondholders will be calculated as:
= ($35/$25) - 1
= 1.4 - 1
= 0.4
= 40%
