Vibrations Dynamics uses vibrations sensitive equipment based on lithography to measure vibrations in building foundations caused by subway, rail, and automobile traffic in major cities of the world. Use a spreadsheet to (a) plot the annual tax curves, and (b) calculate total taxes and the PWtax values at i = 8% per year over an 8-year study period for two depreciation methods: SL with n = 6 years and DDB with n = 8 years. Comment on your total tax and PWtax results. (Note: Neglect any tax effects connected with the salvage value.) The estimates are:
P = $200,000, B = $280,000, S = 20% of P, CFBT = $100,000 per year, Te = 30%.
