Step-by-step explanation:
Straight line depreciation expense = (Cost of asset - Salvage value) / useful life
(30,000 -- 20,000) / 4 = 7,000
Depreciation expense using the double declining method = Depreciation factor x cost of the asset
Depreciation factor = 2 x (1/useful life)
2/4 x 30,000 = $15,000
2022 = 2/4 x (30,000 - 15,000) = 7500
Activity method based on hours worked = (hours worked that year / total hours of the machine) x (Cost of asset - Salvage value)
