Answer:
$63,000
Step-by-step explanation:
Straight line method charges a fixed amount of depreciation for the period the asset is used in the business.
Depreciation Expense = (Costs - Salvage Value) ÷ Estimated useful life
therefore,
2021
Depreciation Expense = $420000 ÷ 4 = $105,000
2022
One month has already expired, therefore the remaining useful life out of 6 years will be 5.
New Depreciable Amount = Cost - Accumulated depreciation to date
= $420,000 - $105,000
= $315,000
Depreciation expense = $315,000 ÷ 5 = $63,000
Conclusion :
the revised depreciation expense for 2022 is $63,000
