2. Ramone and his wife had $72,380.90 in combined gross income in 2010. They had $8,295.00 in various adjustments and deductions. If they are filing jointly, how much income tax do they have to pay for the year?
Let x = taxable income = difference of gross income and deductions T = income tax paid = amount sent to the government Use the "filing jointly" chart on the right side. You'll use the second row of that chart since subtracting $72,380.90-$8,295.00 leads to a value between 16750 and 68000. That second row turns into this equation T=1675+0.15(x-16750) where 16750<x≤68000
