Could answer these 3 question in the shortest way please

4.15 Manufacturing equipment has a capital cost of $43,000, salvage value of $3000, and an asset life of 10 years Compute the depreciation expense for the first 3 years under (a) ac. celerated cost recovery and (b) straight line. 4.16 Business A purchases manufacturing equipment that costs $250,000. Economic life is esti- mated as 5 years with a salvage value of $15,000. This company chooses the accelerated cost recovery method for depreciation. Business B, in competition with company A, buys the same equipment at identical cost. The management of company B uses straight-line depreciation. Determine the yearly depreciation charges and the end-of-year book value for companies A and B.

Life is 6 years or 12.000 hours of production for total solder capacity of 144,000 in.2 during the life period. Salvage value is ex the machine will be retired to secondary and emergency service. Determine the annual depreciation charge and book value for accelerated cost re covery, straight-line, and units of production methods. Plot the "book value" for the three methods. Discuss the merits of book value. 4.15 Manufacturing equipment has a capital cost of $43,000, salvage value of $3000, and an asset life of 10 years Compute the depreciation expense for the first 3 years under (a) ac. celerated cost recovery and (b) straight line. 4.16 Business A purchases manufacturing equipment that costs $250,000.
