Problem-
In recent years, Farr 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)
 | DepreciationMethod
 | 
| 1 | Jan. 1, 2012 | $129,000 | $31,800 | 9 | Straight-line | 
| 2 | July 1, 2013 | 97,000 | 10,700 | 5 | Declining-balance | 
| 3 | Nov. 1, 2013 | 73,270 | 7,270 | 6 | Units-of-activity | 
For the declining-balance method, Farr Company uses the double-declining rate. For the units-of-activity method, total machine hours are expected to be 33,000. Actual hours of use in the first 3 years were: 2013, 680; 2014, 5,170; and 2015, 6,390.
Compute the amount of accumulated depreciation on each machine at December 31, 2015.
If machine 2 was purchased on April 1 instead of July 1, what would be the depreciation expense for this machine in 2013? In 2014?
