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 $117,000. Over its 4-year useful life, the bus is expected to be driven 210,000 miles. Salvage value is expected to be $7, 800. Compute the depreciation cost per unit. Prepare a depreciation schedule assuming actual mileage was: 2017, 46, 800; 2018, 60, 840; 2019, 47, 970; and 2020, 31, 590
