In recent years, Tamarisk 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.

Machine		Acquired		Cost		Salvage Value		Useful Life (in years)		Depreciation Method
1		Jan. 1, 2020		$ 97,200		$ 13,000		8		Straight-line
2		July 1, 2021		89,500		10,000		5		Declining-balance
3		Nov. 1, 2021		86,000		8,000		6		Units-of-activity

For the declining-balance method, Tamarisk Company uses the double-declining rate. For the units-of-activity method, total machine hours are expected to be 39,000. Actual hours of use in the first 3 years were 2021, 700; 2022, 4,300; and 2023, 7,400.
