Answer:
It Sum-of-the -years'-digits method
Explanation:
Depreciation Expense=[Remaining useful life of the asset÷ Sum of the year's digit )×Depreciable cost
Sum-of-the -years'-digits= 3+2+1= 6
Depreciable cost = $24,000- $6,000 = $18,000
Year 1 -Depreciation = [3/6] * $18,000
= $9,000
Year 2-Depreciation =[2/6] * $18,000
= $6000
Year 3-Depreciation =[1/6] * $18,000
= $3000
The sum of years’ digits method is a form of accelerated depreciation that is based on the assumption that the productivity of the asset decreases with the passage of time.
