The gain on the disposal is $2,100.84.
To calculate the gain or loss on the disposal of a fixed asset, you can use the following formula:
Gain or Loss=Selling Price−(Original Cost−Accumulated Depreciation)
In this case:
Gain or Loss=5,102.04−(30,012−27,010.80)
Gain or Loss=5,102.04−3,001.20
Gain or Loss=2,100.84
Since the result is positive, it indicates a gain on the disposal of the fixed asset. Therefore, the gain on the disposal is $2,100.84.
