Answer:
b. $6,000
Step-by-step explanation:
Depreciation is calculated on the cost of asset. Cost of asset includes the transportation and installation cost, because both are necessary in order to function the asset.
Accordingly total cost of asset = $40,000 + $1,000 = $41,000
Salvage value = $5,000
Thus, amount to be depreciated = $41,000 - $5,000 = $36,000
Useful life of the asset = 6 years
Straight line depreciation = $36,000/6 = $6,000 annually.
