Answer:
Gain on Disposal 25,100
Step-by-step explanation:
book value
cost- accumulated depreciation
387,400 - 312,900 = 74,500
trade-in:
equipment 160,000
cash 40,000
total 200,000
gain 200,000 - 74,500 = 125,500
As it lack commercial substance we recognize gain for the portion of cash received doing cross multiplication
200,00 --> generates 125,500 gain
40,000 --> generates X gain
40,000/200,000 x 125,500 = 25,100
