1. Using a spreadsheet program, chart the book value of a $150 000 asset for the first 10 years of its life at declining-balance depreciation rates of 5%, 20%, and 30%.
2. A machine has a life of 30 years, costs €24 5 000, and has a salvage value of €1 0 000 using straight-line depreciation. WTiat depreciation rate will result in the same book value for both the declining-balance and straight-line methods at the end of year 20?
