Answer:
I guess we need to calculate depreciation costs. We can use two methods: straight line depreciation and units of activity depreciation.
Straight line depreciation:
- (purchase value - salvage value) / number of useful years = ($110,000 - $10,000) / 4 years = $100,000 / 4 years = $25,000 per year.
Units of activity depreciation:
- (purchase value - salvage value) / total working hours = ($110,000 - $10,000) / 10,000 working hours = $100,000 / 10,000 working hours = $10 per working hour
