We have the output of book depreciation analysis. The analysis provides annual depreciation amount for an asset using four different methods. We do not know which method was used for book depreciation; however, we have the final output. The sequences of annual depreciation amount for each method A-D are given as follows: A: 4500, 3150, 2212, 1548, 1077 B?:X, X, X, X, C: 2500, 1500, 3000, 1000, 2000 D: 6000, 3600, 1133.33, 1133.33, 1133.33 *For example, the first depreciation amount for method A in the first year is 4500 2 Method B: each year the same amount of depreciation happens. It is unknown and given the symbol x. There are four methods that could potentially have been used: Straight Line, Declining Balance, Declining Balance with Switching, and Unit of Production Method. It is also known that the salvage value is $2,000. a] Which of these five sequences was produced using straight-line method? b] Which of these five sequences was produced using declining balance method without switching? c] Which book depreciation method (or methods) was (or were) used to produce sequence D? d] Given all the information provided before please calculate the cost basis of this asset. You need to provide clear explanations
