A (fictional) country uses the income tax structure below. Tax Bracket (yearly taxable income) $0 to $70,000 over $70,000 Marginal Tax Rate (rate applied to income in this bracket) 5% 15% a. How much will someone pay in taxes if their taxable income is $30,000 a year? $100,000? b. Create a piecewise function that represents total taxes paid (y) as a function of taxable income (x). c. There have been political divisions in recent years. Some people think that the tax structure is unfair because people with higher incomes are paying far more in taxes each year than people with lower incomes. What do you think? Use "effective tax rate" as part of your argument ("effective tax rate" is the percent of a person's income that they pay in taxes). EC 1.1 EC 1.2 EC 1.3 1 2 3 4 1 2 3 4 1 2 3 4
