Question 12 (Essay Worth 10 points)
(Federal Income Taxes and Piecewise Functions
MC) The piecewise function represents the amount of taxes owed, f(x), as a function of the taxable income, x.
Use the marginal tax rate chart or the piecewise function to answer the questions.

Part A: Using the method of your choice, demonstrate how to calculate the amount of taxes owed on a taxable income of $31,000. Show all work. (4 points)

Part B: Using the taxes owed from part A, determine the effective tax rate. Show all work. (4 points)

Part C: Compare the piecewise function to the marginal tax rate chart. How is the marginal tax rate chart represented in the piecewise function?
