Answer:
C. $200,000
Step-by-step explanation:
Straight Line depreciation is a method of depreciation in which the cost of the asset net of residual value is divided over useful life.
In this question the tractor cost is $220,000 which needs to be depreciated after deducting residual value from cost of Tractor.
Use following Formula to calculate the straight line depreciation.
Depreciation rate = ( Cost - Salvage Value ) / useful life = ($220,000 - $20,000) / 8 = $25,000 per year
Depreciated in 8 years = $25,000 x 8 = $200,000
We can also consider the depreciable value as the total depreciation in 8 years because the useful life of the tractor is also 8 years.
