Final answer:
Julie Miles will have $39.80 withheld from her weekly paycheck for federal income tax.
Step-by-step explanation:
To calculate the amount withheld from Julie Miles' weekly paycheck for federal income tax, we need to use the tax withholding tables provided by the IRS. Let's assume that Julie is paid on a weekly basis and is married filing jointly with two allowances.
According to the 2021 tax withholding tables, for a single person earning $445.20 a week, the federal income tax withholding would be about $52.38 per week. However, since Julie is married filing jointly with two allowances, her withholding amount will be lower. Therefore, the correct answer is $39.80 (Option B).
