Answer:
$72440
Explanation:
aftertax salvage value = sales price of the machine - tax(sales price - book value)
Straight line depreciation expense = (Cost of asset - Salvage value) / useful life
( $168,000 - 0) / 7 = $24,000
Depreciation expense each year would be $24,000
Accumulated depreciation in year 3 = $24,000 x 3 = $72,000
Book value in year 3 = $168,000 - $72,000 = $96,000
book value = 96,000
$65,000 - 0.24 x ( $65,000 - $96,000)
