Given that
Federal income tax =4594.84
Social security tax withheld = 2397.52.
Medicare tax withheld =479.14.
Recall that The Federal Insurance Contributions Act (FICA) is a U.S. law that mandates a payroll tax on the paychecks of employees, as well as contributions from employers, to fund the Social Security and Medicare programs.
The money was paid in FICA tax =Federal income tax +Social security tax + Medicare tax
Hence the money was paid in FICA tax is $7471.50.
