n recent years, Crane Company has purchased three machines. Because of frequent employee turnover in the accounting department, a different accountant was in charge of selecting the depreciation method for each machine, and various methods have been used. Information concerning the machines is summarized in the table below.

3		Nov. 1, 2021		71,900		7,900		6		Units-of-activity

For the declining-balance method, Crane Company uses the double-declining rate. For the units-of-activity method, total machine hours are expected to be 32,000. Actual hours of use in the first 3 years were: 2021, 810; 2022, 6,400; and 2023, 7,900.
