TEST YOUR UNDERSTADING FOR EXAMPLE 3.3 The State of New York also has an income tax. The tax table for New York shows that a single New York resident with a taxable income of 15,000 owes 671 in New York income tax. If the taxable income is 15,500, then the table shows a tax liability of 701. Assume that the state tax is a linear function of taxable income, and find the tax owed if the taxable income is 15,350. EXAMPLE 3.3 OKLAHOMA INCOME TAX The amount of income tax T=T(l), in dollars, owed to the state of Oklahoma is a linear function of the taxable income l, in dollars, at least over a suitably restricted range of incomes. According to the Oklahoma Income Tax table for the year 2015, a single Oklahoma resident taxpayer with a taxable income of 15,000 owes 579 in Oklahoma income tax. In functional notation, this is T(15,000)=579. If the taxable income is 15,500, then the table shows a tax liability of 605. Part 1 Calculate the rate of change in T with respect to I, and explain in practical terms what it means. Part 2 How much does the taxpayer owe if the taxable income is 15,350?
