Montello Inc. purchases a delivery truck for $25,000. The truck has a salvage value of $6,000 and is expected to be driven for 125,000 miles. Montello uses the units-of production depreciation method, and in year one the company expects the truck to be driven for 26,000 miles; in year two, 30,000 miles; and in year three, 40,000 miles. Consider how the purchase of the truck will impact Montello’s depreciation expense each year and what the truck’s book value will be each year after depreciation expense is recorded.
