Answer:
$9000
Step-by-step explanation:
Depreciation is a systematic allocation of the cost of an asset over its useful life. One method of depreciation is the straight line method where the value of an asset is uniformly and gradually written off over its useful life
Working
Cost of asset - $90000
Useful life - 9years
Salvage value - $9000
Fiscal year - (Jan 1- Dec 31)
Depreciable amount- (90000-9000)= $81000
Annual depreciation (straight line ) 81000/9 = $9000
December 31 2017 depreciation expense = $9000*1/2 = 4500
Decemebr 31 2018 depreciation expense = $9000
