On January 2, 2007, Lapar Corporation purchased a machine for $50,000. Lapar paid shipping expenses of $500, as well as installation costs of $1,200. The company estimated that the machine would have a useful life of 10 years and a salvage value of $3,000. In January 2008, the company made additions costing $3,600 to the machine in order to comply with pollution-control ordinances. These additions neither prolonged the life of the machine nor increased the salvage value. Required If Lapar records depreciation under the straight-line method, how much is the depreciation expense for 2008?
