Answer:
Anna will pay $4,000 in taxes.
Step-by-step explanation:
Calculate her annual earnings:
Anna earns $10 per hour and works 40 hours per week. So, her weekly earnings are:
$10 per hour × 40 hours/week = $400/week
Since she works 50 weeks per year:
$400/week × 50 weeks/year = $20,000/year
Calculate her tax liability:
Anna's tax rate is 20 percent. To find the amount she will pay in taxes, we'll apply this tax rate to her annual earnings:
20% of $20,000 = 0.20 × $20,000 = $4,000
