Answer:
$575
Step-by-step explanation:
Straight line method charges a fixed amount of depreciation using the formula :
Depreciation expense = (Cost - Residual Value) ÷ Useful Life
2017
Deprecation expense = $820
2018
Deprecation expense = $820
2019
Calculate depreciable amount :
New depreciable amount = Previous Depreciable Amount - Accumulated depreciation - Increase in Residual amount
= $4,700 - $600 - $1,640 - $100
= $2,300
Determine the New useful life :
Since 2 years have already expired, the new useful life out of the revised 6 years is 4.
Depreciation Expense calculation :
Depreciation Expense = Depreciable Amount ÷ Useful Life
= $2,300 ÷ 4
= $575
Conclusion :
The amount of depreciation expense for the year 2019 is $575
