Compute the depreciation each year of a machine that costs $50,000 to purchase, and $4,000 to install with an 8-year life. Use the DDB method (multiplier = 2) switching to straight line depreciation when appropriate. Assume a salvage value of $0. D_1 = D_2 = D_3 = D_4= D_5 = D_6= D_7 = D_8 = Compute the depreciation each year of a machine that costs $50,000 to purchase, and $4,000 to install with an 8-year life.
