In recent years, Ivanhoe 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 below. Bus Acquired Cost Residual Value Useful Life in Years Depreciation Method 1 1 1/1/18 5 95,600 125,000 6,000 10,500 2 1/1/18 4 Straight-line Declining-balance Units-of-activity 3 1/1/19 90.600 8,000 4 For the declining-balance method, the company uses the double-declining rate. For the units-of-activity method, total miles are expected to be 118,000. Actual miles of use in the first 3 years were: 2019,27,500; 2020, 36,000; and 2021, 33,000 Calculate depreciable cost per mile for Bus 3. (Round answer to 2 decimal places, eg. 0.50.) Depreciable cost per mile Compute the amount of accumulated depreciation on each bus at December 31, 2020.
