Vedmedyk [2.9K]

Answer:

$413.83

Step-by-step explanation:

Your earnings for the two weeks are

7.25(40)(2) = 580

The deductions for FICA will be

0.0765(580) = 44.37

The deductions for federal withholding will be

0.14(580) = 81.2

The deductions for state withholding will be

0.07(580) = 40.6

This makes your realized income

580-(44.37+81.2+40.6) = 580-166.17 = 413.83
