Brittney, this is the solution:
Salma's income = $ 20,000
1st bracket = 10% for the first $ 8,000
2nd bracket = 14% for the amount over $ 8,000
Therefore,
Income tax last year = 8,000 * 0.1 + (20,000 - 8,000) * 0.14
Income tax las year = 800 + 1,680
Income tax last year = 2,480
Salma will pay $ 2,480 in income tax for last year
