Kim earned $19,000 last year. If the first $10,000 is taxed at 9% and income above that is taxed at 19%, how
much does Kim owe in tax?

$2,610

Step-by-step explanation:

total money earned: $19,000

she was taxes 9% on the first $10,000 which is equal to:

$1,710 in taxes for the $9,000 earned after the first $10,000

She owes in taxes a total of:

$2,610
