·         1/25/20X3   Sales on Account: 300 units @ $8.50 = $2,550


The company president examined the computer generated journal entries for these transactions and was confused by the absence of a Purchases account.

5. Depreciation methods. Mike Davis Enterprises purchased a delivery van for $40,000 in January 20X7. The van was estimated to have a service life of 5 years and a resid­ual value of $6,000. The company is planning to drive the van 20,000 miles annually. Compute depreciation expense for 20X8 by using each of the following methods:


a. Units of output, assuming 17,000 miles were driven during 20X8


b. Straight line


c. Double declining balance


6. Depreciation computations. Alpha Alpha Alpha, a college fraternity, purchased a new heavy duty washing machine on January 1, 20X3. The machine, which cost $2,000, had an estimated residual value of $100 and an estimated service life of 4 years (1,800 washing cycles). Calculate the following:


a. The machine’s book value on December 31, 20X5, assuming use of the straight line depreciation method


b. Depreciation expense for 20X4, assuming use of the units of output depreciation method. Actual washing cycles in 20X4 totaled 500.


c. Accumulated depreciation on December 31, 20X5, assuming use of the double declining balance depreciation method.




7. Depreciation computations: change in estimate. Aussie Imports purchased a specialized piece of machinery for $50,000 on January 1, 20X3. At the time of acquisition, the machine was estimated to have a service life of 5 years (25,000 operating hours) and a residual value of $5,000. During the 5 years of operations (20X3 20X7), the machine was used for 5,100, 4,800, 3,200, 6,000, and 5,900 hours, respectively.




a. Compute depreciation for 20X3 20X7 by using the following methods: straight line, units of output, and double declining balance.


b. On January 1, 20X5, management shortened the remaining service life of the machine to 15 months. Assuming use of the straight line method, compute the company’s depreciation expense for 20X5.

c. Briefly describe what you would have done differently in part (a) if Aussie Imports had paid $47,800 for the machinery rather than $50,000 In addition, assume that the company incurred $800 of freight charges $1,400 for machine setup and testing, and $300 for insurance during the first year of use.
