a) For each tax scheme, compute (or estimate if necessary) the amount of tax for income of $5,000 and $50,000. b) For each tax scheme, plot the other two graphs corresponding to that scheme. c) Give formulas for as many of the functions above as possible (some will be approximations) d) For each tax scheme, comment in whatever aspects strike you as interesting, inappropriate, etc. a) For each tax scheme, compute (or estimate if necessary) the amount of tax for income of $5,000 and $50,000. b) For each tax scheme, plot the other two graphs corresponding to that scheme. c) Give formulas for as many of the functions above as possible (some will be approximations) d) For each tax scheme, comment in whatever aspects strike you as interesting, inappropriate, etc
