Answer:
a.
Cash $21080 Dr
Accumulated Depreciation-Machine $24080 Dr
Gain on Disposal $2160 Cr
Machine account $43000 Cr
b.
Cash $11080 Dr
Accumulated Depreciation-Machine $24080 Dr
Loss on Disposal $7840 Dr
Machine account $43000 Cr
Step-by-step explanation:
The asset is being sold off by the company which will cause the business to write off the asset from the books and credit it. The accumulated depreciation is a contra asset account and it will be debited to close this account.
The carrying value of the asset = Cost - Accumulated Depreciation
Carrying value = 43000 - 24080 = $18920
If the sales proceeds is more than the carrying value there is a gain on disposal and vice versa.
a.
Gain/loss on disposal = 21080 - 18920 = $2160 gain
b.
Gain/loss on disposal = 11080 - 18920 = -$7840 loss
