Answer:
depreciation.
Step-by-step explanation:
Depreciation is the reduction in value of a long term asset as it is used over the years
for example, as one uses a vehicle, its value reduces due to wear and tear
depreciation is a way of expensing the cost of purchasing an asset
types of depreciation
Straight line depreciation expense = (Cost of asset - Salvage value) / useful life
Activity method based on output = (output produced that year / total output of the machine) x (Cost of asset - Salvage value)
Activity method based on hours worked = (hours worked that year / total hours of the machine) x (Cost of asset - Salvage value)
Sum-of-the-year digits = (remaining useful life / sum of the years ) x (Cost of asset - Salvage value)
