Answer:
$1302
Explanation:
We have been given that employees in 2012 paid 4.2% of their gross wages towards social security (FICA tax), while employers paid another 6.2%. We are asked to find the amount paid by someone towards social security out of their gross wages earning $31,000 a year.
The amount paid by a person earning $31,000 a year towards FICA tax would be 4.2% of $31,000 because employers pay from their own treasury.



Therefore, the person will pay $1302 towards social security.
