Calculations are done on a nominal basis‚ converting the salvage value estimate from a real to a nominal value (638 = 500(1.05)5) using the 5% inflation estimate; salvage = book value so no taxes are incurred on salvage. 2. Depreciation is calculated at [4‚000 – 638 (salvage) ]/ 5 = 672.4 per year. 3. Cars sales occur in year 1
