What is depreciation?
Depreciation is the portion of the asset value that is deemed to be consumed and shown as an expense in the year under review.
Under the straight-line depreciation method, depreciation per year, which is fixed, is the asset value minus the residual value divided by the useful life of the asset
depreciation=(asset value-residual value)/useful life
asset value=$78,000
residual value=$3000
useful life=5
depreciation=($78000-$3,000)/5
depreciation=$15,000
total depreciation for 4 years=$15,000*4
total depreciation for 4 years=$60,000
book value after 4 years=$78,000-$60,000
book value after 4 years=$18,000
profit/(loss)=proceeds from disposal-book value after 4 years
profit/(loss)=$8,000-$18,000
profit/(loss)=-$10,000
Option C is the most appropriate
