Consider an asset that costs $680,000 and is depreciated straight-line to zero over its nine-year tax life. The asset is to be used in a five-year project; at the end of the project, the asset can be sold for $143,000. If the relevant tax rate is 24 percent, what is the aftertax cash flow from the sale of this asset? (Do not round intermediate calculations and round your answer to the nearest whole number, e.g., 32.)

(i know the solving for it but why dont we deduct 143,000 from 680,000 when calculating annual depreciation? isnt it (initial cost - salvage)/number of years?)
