Information concerning the buses is shown as follows Salvage Value Useful Life in Years Bus Acquired Cost Method $96,000 110,000 92,000 6,000 10,000 8,000 Straight-line Declining-balance Units-of-activity For the declining-baae method, the company uses the double-declining rate. For the units-of-activity method, total miles are expected to be 120,000. Actual miles of use in the first 3 years were 2018, 24,000; 2019, 34,000; and 2020, 30,000 For Bus #3, calculate depreciation expense per mile under units-of-activity method. (Round answer to 2 decimal places, eg, 0.50.) Depreciation expense per mile Compute the amount of accumulated depreciation on each bus at December 31, 2019. (Round depreciation cost per unit to 2 decimal places, e.g. 0.50 and depreciation rate to O decima places, e.g. 15%. Round final answers to 0 decimal places, eg. 2,125.)
