Calculate the amount of depreciation to report during the year ended December 31,2010, for equipment that was purchased at a cost of $33,000 on September 1,2010. The equipment has a estimated residual value of $3,000 and an estimated useful life of five years or 20,000 hours. Assume the equipment was used for 1,000 hours from September 1 to December 31 and the company uses: straight-line, double-declining-balance, or units-of-production depreciation.
