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.

Answer:
f-¹(x) =(1-5x) /3x.
Step-by-step explanation:
f(x)=1/(3x+5)
Let y=1/(3x+5)
Exchanging x and y,
x=1/(3y+5)
3y+1=1/x
3y=1/x-5
3y=(1-5x) /x
y=(1-5x)/3x
f-¹(x) =(1-5x) /3x.
