Answer:
gain of $5,000
Explanation:
Wolf's gain = fair market value - book value = $45,000 - $40,000 = $5,000
a company must determine the gain or loss of an exchange transaction using the asset's book value and comparing it against its fair market value. If the FMV is higher than the book value, the company will recognize a gain. If the FMV is lower than the book value, then the company will recognize a loss.
