Final answer:
The depreciation expense for the service truck cannot be determined without additional information.
Step-by-step explanation:
To calculate the depreciation expense for the service truck, we need to determine the useful life of the truck and the depreciation method being used. Assuming the straight-line depreciation method is being used with a useful life of 10 years, we can calculate the depreciation expense as follows:
Depreciation Expense = (Cost - Salvage Value) / Useful Life
Depreciation Expense = ($24,000 - $0) / 10 = $2,400 per year.
Therefore, the correct answer is option 3) Cannot be determined without additional information.
