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.
[tex]f(x)=\left\{\begin{matrix}0.062x&,if\ \ 0<x\leq113700 \\ 7&,if\ \ 113700<x\end{matrix}\right.[/tex]
Substitute the values then we get
[tex]f(50000)=0.062 (50000)=[/tex]$3100
When the income of someone is $50000 then you Ā paid Ā the security tax $3100.
