Gordon Chemicals Company acquires a delivery truck at a cost of $38, 400 on January 1, 2017. The truck is expected to have a salvage value of $2, 400 at the end of its 4-year useful life. Assuming the declining-balance depreciation rate is double the straight-line rate, compute annual depreciation for the first and second years under the declining-balance method. Whippet Bus Lines uses the units-of-activity method in depreciating its buses. One bus was purchased on January 1, 2017, at a cost of $101, 000. Over its 4-year useful life, the bus is expected to be driven 186, 000 miles. Salvage value is expected to be $8, 000. Compute the depreciation cost per unit. Prepare a depreciation schedule assuming actual mileage was: 2017, 40, 400; 2018, 52, 520; 2019, 41, 410; and 2020, 27, 270
