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 question. Tax Bracket Marginal Tax Rate $0–$10,275 10% $10,276–$41,175 12% $41,176–$89,075 22% $89,076–$170,050 24% $170,051–$215,950 32% $215,951–$539,900 35% > $539,901 37% A piecewise function f of x defined by seven pieces. Part 1 is 0.10x for 0 is less than x is less than or equal to 10,275. Part 2 is 0.12x minus 205.50 for 10,276 is less than or equal to x is less than or equal to 41,175. Part 3 is 0.22x minus 4,323 for 41,176 is less than or equal to x is less than or equal to 89,075. Part 4 is 0.24x minus 6,104.50 for 89,076 is less than or equal to x is less than or equal to 170,050. Part 5 is 0.32x minus 19,708.50 for 170,051 is less than or equal to x is less than or equal to 215,950. Part 6 is 035x minus 26,187 for 215,951 is less than or equal to x is less than or equal to 539,900. Part 7 is 0.37x minus 36,985 for x is greater than or equal to 539,901. Determine the effective tax rate for a taxable income of $180,900. Round the final answer to the nearest hundredth. 19.50% 20.00% 21.11% 32.00%
