Answer 2

First Year - $28,000 with a 7.25% depreciation = 28000 * 7.25% = 2,030 - 28000 = $25,970 Second Year - $25,970 with a 7.25% depreciation = 25970 * 7.25% =1883 - 25970 = $24,087 Third Year - $24,087 with a 7.25% depreciation = 24087 * 7.25% = 1746 - 24087 = $22,341 Fourth Year = $22,341 with a 7.25% depreciation = 1620 - 22341 = $20,721 Fifth Year = $20.721 with a 7.25% depreciation = 1502 - 20721 = $19,219
