Answer:
The book value of the machine at the end of year 2 is $35,000
Step-by-step explanation:
Straight line method depreciates the asset on its useful life after deducting salvage value from the cost of the asset.
Depreciation per year = ( Cost of Machine - Residual Value ) / Useful life
Depreciation per year = ( $42,000 - $7,000 ) / 10 years
Depreciation per year = $3,500 per year
Book value of machine at the end of year 2 = $42,000 - ( $3,500 x 2 )
Book value of machine at the end of year 2 = $42,000 - $7,000
Book value of machine at the end of year 2 = $35,000
