The United States uses a "progressive" tax system, meaning that the tax rate increases as taxable income increases. However, the tax rate is "marginal," meaning that only the income above certain thresholds is taxed at the higher rate. See the class notes for more on this.

You are asked to use the information in the following table to calculate the taxes payable for 4 different scenarios, described below. For each scenario, indicate the total tax and how you calculated that.

Taxable personal income, married, filing jointly ($)	Taxable personal income, single ($)	Marginal tax rate (%)
0 to 22,000	0 to 11,000	10
22,001 to 89,450	11,001 to 44,725	12
89,451 to 190,750	44,726 to 95,375	22
190,751 to 364,200	95,376 to 182,100	24
364,201 to 462,500	182,201 to 231,250	32
462,501 to 693,750	231,251 to 578,125	35
