Final answer:
Mary Lou's total FICA tax withheld in 2022 would be $5,202.
Step-by-step explanation:
To calculate Mary Lou's total FICA tax withheld in 2022, we need to determine her gross annual income and then apply the appropriate rates for Social Security and Medicare taxes. Her gross annual income can be calculated by adding up her earnings from each job. In this case, Mary Lou earned $30,000, $27,000, and $11,000 from her three jobs, respectively. Adding these amounts together gives us a gross annual income of $68,000.
To calculate the Social Security tax, we multiply the gross annual income by the tax rate of 6.2%. The Social Security tax withheld would be 6.2% of $68,000, which is $4,216.
To calculate the Medicare tax, we multiply the gross annual income by the tax rate of 1.45%. The Medicare tax withheld would be 1.45% of $68,000, which is $986.
Therefore, Mary Lou's total FICA tax withheld in 2022 would be the sum of the Social Security and Medicare taxes, which is $4,216 + $986 = $5,202.
