Answer:
Depreciation expense in 2021 =$2420.50
Depreciation expense in 2019 = $1442
Explanation:
The following steps would be taken to determine the answer
1. Calculate depreciation expense given the initial information
2. calculate the accumulated depreciation by the second year. Accumulated depreciation is sum of depreciation expense
3. subtract the accumulated depreciation from the cost price of the asset. This would give the book value
4. calculate the depreciation expense using the new information and the book value
Straight line depreciation expense = (Cost of asset - Salvage value) / useful life
($8,240 - $1030) / 5 = $1442
Accumulated depreciation by January 2021 = $1442 x 2 = $2884
Book value = $8,240 - $2884 = $5356
New useful life = 2 years
Salvage value = $515
Depreciation expense in 2021 = ($5356 - $515) / 2 = $2420.50
