Problem 10-02A a1-b 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. Bus Acquired Cost Salvage Value Useful Life in Years 1 1/1/18 $ 96,000 $6,000 5 2 1/1/18 3 1/1/19 110,000 92,000 10,000 8,000 4 5 Depreciation Method Straight-line Declining-balance Units-of-activity For the declining-balance method, the company uses the double-declining rate.
