Final answer:
To calculate the Social Security deduction, multiply the pay amount by 6.2%. For Medicare deduction, multiply the pay amount by 1.45%.
Step-by-step explanation:
To calculate the Social Security and Medicare deductions for the employee, we need to use the given tax rates. The Social Security deduction is 6.2% and the Medicare deduction is 1.45%, both based on the gross annual income. In this case, the pay amount for this period is $9000.
To calculate the Social Security deduction, we multiply the pay amount by 6.2%: $9000 * 0.062 = $558.00.
To calculate the Medicare deduction, we multiply the pay amount by 1.45%: $9000 * 0.0145 = $130.50.
