Final answer:
To calculate Jeffrey's total Social Security deductions for the year, we multiply his semimonthly salary by the number of semimonths in a year and then calculate the Social Security deduction, which is 6.2% of the gross annual salary. The total of his Social Security deductions for the year is $3,246.52.
Step-by-step explanation:
To calculate the total Social Security deductions for the year, we need to first calculate the gross annual salary. A semimonthly salary means that Jeffrey earns his salary twice a month. So, to get the annual salary, we multiply the semimonthly salary by the number of semimonths in a year: $2181.80 × 24 = $52,363.20.
Next, we calculate the Social Security deduction, which is 6.2% of the gross annual salary: 6.2% × $52,363.20 = $3,246.52.
Therefore, the total of Jeffrey's Social Security deductions for the year is $3,246.52.
