Answer:
Robert had to pay $ 4,603.53 to social security.
Explanation:
To determine the amount Robert paid to social security, knowing that he has three jobs, one at young's grocery where he earned $ 5,804, another as a waiter at the A & B restaurant where he earned $ 12,445, and another where he earned $ 56,002 working for a CCD communications, and also knowing that you pay 6.2% of your income to social security, the following calculation must be performed:
(5,804 + 12,445 + 56,002) x 0.062 = X
74,251 x 0.062 = X
4,603.53 = X
Thus, Robert had to pay $ 4,603.53 to social security.
