Answer:
Amount of depreciation expense =$5,250
Step-by-step explanation:
Under the straight line method the same amount is charged as depreciation expense over the estimated useful life of the asset
Initial depreciation = cost - salvage value /number of years
= (25,000 -5000)/5
= 4000 per year
Accumulated depreciation for 4 years= 4000× 3 = 12,000
Revised depreciation = (25,000 -12,000 - 2500)/2
=$5250 per year
Amount of depreciation expense for year 4 =$5250
