Find the net pay:Hours worked -- 35, Hourly Wage --$9.50, Federal tax --$35.02, Social Security -- $25.44
Llana [10]

Answer:

The net pay is $272.04 .

Step-by-step explanation:

As given in the question

Hours worked - 35, Hourly Wage -$9.50 .

Thus

Gross pay = Hours worked × Hourly Wage

Put all the values in the above

Gross pay = 35 × $9.50

                 = $ 332.5

As given

Federal tax - $35.02, Social Security tax  - $25.44

Thus

Net pay =  Gross pay -  Federal tax - Social Security tax

Put all the values in the above

Net pay = $ 332.5 - $35.02 -  $25.44

             = $332.5 - $60.46

             = $ 272.04

Therefore the net pay is $272.04 .
