Answer:
$3100
Step-by-step explanation:
We are given that
If you earned upto $113,700 in 2013 from an employer then your security tax=6.2% of income
If you earned over $113,700 then, you paid amount of tax=$7049.40
We have to find the social security tax when you would made $50000.
Let x be the income and f(x) be the amount of tax.
Substitute the values then we get
$3100
When the income of someone is $50000 then you paid the security tax $3100.
