Answer:
$48,940
Step-by-step explanation:
Straight line depreciation method charges a fixed amount as depreciation expense using the formula :
Depreciation expense = (Cost - Residual Value) ÷ Estimated useful life
therefore,
2019
Depreciation expense = $22,120
2020
Depreciation expense = $22,120
2021
New depreciable amount = Cost - Accumulated deprecation - New Residual Amount
= $240,000 - $44,240
= $195,760
New Useful life = Remaining years
= 6 - 2
= 4
therefore,
Depreciation expense = $195,760 ÷ 4
= $48,940
