If Jackie has a taxable income of between $9,875 and $40,125 in 2020, write an equation representing the amount of income tax that Jackie owes.
What tax tables are you using ?
2020 tax table put that amount of income in the 12% bracket
income below 9875 is taxed at 10 % (from the tables)
tax total = .10 (9875) + .12 (income - 9875)
