On January 1, 2017, Ayayai SA purchased the following two machines for use in its production process. Machine A: The cash price of this machine was R$42,600. Related expenditures included: sales tax R$3,600, shipping costs R$ 140, insurance during shipping R$ 120, installation and testing costs R$100, and R$ 120 of oil and lubricants to be used with the machinery during its first year of operations. Ayayai estimates that the useful life of the machine is 5 years with a R$4,700 residual value remaining at the end of that time period. Assume that the straight-line method of depreciation is used. The recorded cost of this machine was R$ 145,600. Ayayai estimates that the useful life of the machine is 4 years with a R$9,100 residual value remaining at the end of that time period. Machine B: Prepare the following for Machine A. (Round answers to 0 decimal places, e.g. 2,125. Credit account titles are automatically indented when amount is entered. Do not indent manually.) 1. The journal entry to record its purchase on January 1, 2017. 2. The journal entry to record annual depreciation at December 31, 2017. No. Account Titles and Explanation Debit Credit 1. Equipment 46680 Cash 46680 2. Depreciation Expense 8396 Accumulated Depreciati 8396 Calculate the amount of depreciation expense that Ayayai should record for Machine B each year of its useful life under the following assumptions. (Round answers to 0 decimal places, e.g. 2,125. Round cost per unit to 2 decimal place, e.g. 1.25.) (1) Ayayai uses the straight-line method of depreciation. (2) Ayayai uses the declining-balance method. The rate used is twice the straight-line rate. (3) Ayayai uses the units-of-activity method and estimates that the useful life of the machine is 135,900 units. Actual usage is as follows: 2017, 48,000 units; 2018, 37,200 units; 2019, 29,300 units; 2020, 21,400 units. 2017 2018 2019 2020 Straight-line method R$ R$ R$ R$ Declining-balance method R$ R$ R$ R$L R$ R$ Units-of-activity method R$ R$ Which method used to calculate depreciation on Machine reports the highest amount of depreciation expense : In Year 1 (2017) Declining-balance method In Year 4 (2020) Straight-line method Over the 4-year period All three of the methods are equal
