A company purchased equipment for $50,000 on January 1 of its first year. The equipment’s original estimated useful life is 8 years and its estimated salvage value is $10,000. The company uses the straight-line method of depreciation. On December 31 of its second year, before year-end adjusting entries have been recorded, the company decides to shorten the estimated useful life by 3 years giving it a total life of 5 years. The company did not change the salvage value and continues to use the straight-line method. How much depreciation expense should be recorded for the second year?
