Suppose FedEx purchased equipment on January 1, 20X7, for $44,000. The expected useful life of the equipment is 10 years or 100,000 units of production, and its residual value is $4,000. Under 3 depreciation methods, the annual depreciation expense and the balance of accumulated depreciation at the end of 20X7 and 20X8 are as follows: Required: 1) Identify the depreciation method used in each instance, and show the equation ans computation for each. (Round to the nearest dollar) 2) Assume continued use of the same method through year 20X9. Determine the annual depreciation expense, accumulated depreciation, and book value of the equipment for 20X7 through 20X9 under each method, assuming 12, units of production in 20X9 Suppose FedEx purchased equipment on January 1, 20X7, for $44,000.
