Answer:
Juilette will pay tax $8800 in a year
Explanation:
Juilette earns $4500 monthly. It means she earns $4500*12=$54000 per year.
She gets a tax free allowance of $10000 per year and pays tax at 20% on the rest.
Since she earns more than $10000 per year, the taxable amount is
$54000 - $10000 = $44000
She must pay 20% of $44000:
20% of $44000 = 20 * $44000 / 100 = $8800
