Information concerning the machines is summarized in the table below.

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 34,000. Actual hours of use in the first 3 years were: 2013, 660; 2014, 5,040; and 2015, 6,300.
