Detailed Answer
(b) The cash price of the new machine represents its fair
market value (FMV). The FMV of the old machine can be determined
by subtracting the cash portion of the purchase price
($6,000) from the total cost of the new machine: $20,500 –
$6,000 = $14,500. Since the book value of the machine
($16,800) exceeds its FMV on the date of the trade-in ($14,500),
the difference of $2,300 must be recognized as a loss.
