Final answer:
The question cannot be accurately answered without the current IRS withholding tables and the tax year. It's a question likely designed to practice payroll procedures or to use tax tables.
Step-by-step explanation:
The question is asking to calculate the amount of federal income tax withheld from the weekly earnings of Maggie Brown, a customer service representative at Kelly's Floral Designs who is single, earns $455 weekly, and claims 2 allowances. The withholding amount is determined by the IRS withholding tables, which are typically found in IRS Publication 15 (Circular E), Employer's Tax Guide. However, to provide an accurate answer, one would need the current version of the IRS withholding tables and the tax year in question. Since this specific information isn't provided, we cannot calculate the exact amount. The purpose of the question seems to be a test of understanding payroll procedures or to practice using tax tables.
