Final answer:
Without further information on salvage value or depreciation method, under the straight-line method, Randy would depreciate his warehouse at $6,250 per year for each of the 40 years, including the first and the 40th year.
Step-by-step explanation:
To calculate the depreciation for the current year and the 40th year on a commercial warehouse purchased for $250,000 by Randy, we would need to know the method of depreciation being used. Common methods include straight-line depreciation, declining balance, and sum-of-the-years'-digits, among others.
So, the yearly depreciation would be:
Depreciation per year = Purchase Price / Useful Life = $250,000 / 40 years = $6,250 per year.
A) Depreciation for the current year: $6,250
B) Depreciation in the 40th year: same as any other year, $6,250, because the straight-line method results in the same amount every year.
