Southern Pizza bought a used Ford delivery van on January 2, 2021, for $21,000. The van was expected to remain in service for four years (47,500 miles). At the end of its useful life, Southern management estimated that the van's residual value would be $2,000. The van traveled 15,000 miles the first year, 10,000 miles the second year, 12,500 miles the third year, and 10,000 miles in the fourth year. Read the requirements. 1. Prepare a schedule of depreciation expense per year for the van under the three depreciation methods. (For units-of-production and double-declining-balance methods, round to the nearest two decimal places after each step of the calculation.) 2. Which method best tracks the wear and tear on the van? 3. Which method would Southern prefer to use for income tax purposes? Explain your reasoning in detail. Requirement 1. Prepare a schedule of depreciation expense per year for the van under the three depreciation methods. Prepare a schedule of depreciation expense per year for the van under the straight-line method. (Complete all input fields. Enter a 0 for any zero balances.) Prepare a schedule of depreciation expense per year for the van under the units-of-production (UOP) method. (Round any intermediary computations to two decimal places, X.XX, and your final answers to the nearest whole dollar. Complete all input fields. Enter a 0 for any zero balances.) Prepare a schedule of depreciation expense per year for the van under the double-declining-balance (DDB) method. (Round any intermediary computations to two decimal places, X.XXX, and your final answers to the nearest whole dollar. Complete all input fields. Enter a 0 for any zero balances.) Requirement 2. Which method best tracks the wear and tear on the van? The method tracks the wear and tear on the van most closely. Requirement 3. Which method would Southern prefer to use for income tax purposes? Explain your reasoning in detail. For income tax purposes, Southern's would prefer the method because it provides the depreciation, and thus, the tax deductions in the early life of the asset
