Answer:
The book value at the end of year 3 is $100,000
Explanation:
Yearly Depreciation =(cost+cost of dismantling-salvage value)/useful life
cost is $200,000
cost of dismantling is $5000
salvage value is $30000
useful life is 5 years
Yearly depreciation=(200000+5000-30000)/5
Yearly depreciation=$35000
Depreciation for three years=$35000*3
=$105000
Book value at the end of year 3=total cost of machine-three years' depreciation
Book value at end of year 3=$200000+$5000-$105000
Book value at the end of year 3=$100,000
