Problem 9-2A In recent years, Avery Transportation purchased three used buses. Because of frequent turnover in the accounting department, a different accountant selected the depreciation method for each bus, and various methods were selected. Information concerning the buses is summarized as follows. Salvage Value Useful Life in Years Bus Acquired 1/1/13 1/1/13 1/1/14 Cost 596,500 120,000 95,110 $8,000 10,500 8,100 Depreciation Method Straight-line Declining-balance Units-of-activity For the declining-balance method, the company uses the double-declining rate. For the units of activity method, total miles are expected to be 124,300. Actual miles of use in the first 3 years were: 2014, 26,400; 2015, 32,900; and 2016, 32,900. Calculate depreciation expense per mile under units-of-activity method. (Round answer to 2 decimal places, e.. 0.50.) Depreciation expenses per mile Compute the amount of accumulated depreciation on each bus at December 31, 2015. (Round answers to o decimal places, e.g. 2,125.) 2015 BUS 1 s BUS 2 s BUS 3
