Final answer:
Robert contributes $82.36 from each of his semimonthly paychecks towards his health care. To find his annual contribution, we multiply this amount by 24 (the number of semimonthly periods in a year), resulting in $1976.64 as his total annual contribution to health care.
Step-by-step explanation:
Robert contributes $82.36 to his individual health care twice a month, as part of his semimonthly paychecks. To calculate his annual contribution, we will multiply this amount by the number of semimonthly periods in a year.
Since there are 12 months in a year and 2 semimonthly periods per month, we have:
12 months x 2 semimonthly periods/month = 24 semimonthly periods/year
Now, we will calculate the total annual contribution by multiplying the number of semimonthly periods by the semimonthly deduction:
24 semimonthly periods/year x $82.36/contribution = $1976.64 annually
Therefore, Robert contributes $1976.64 to his individual health care annually.
