Answer:

Hence her net pay= $ 560-$145.64

                              =$ 414.36

Step-by-step explanation:

Ally worked 40 hours for $14/h.

So her total pay i.e. her gross pay is: $(40×14)=$ 560.

she paid $72.80 in federal tax, $34.72 in social security tax, and $8.12 in Medicare tax and  she had $30 taken out for retirement savings.

We are asked to find out her net pay.

" Net pay is an employee’s earnings after all deductions are taken out.

Deductions such as the FICA mandated Social Security tax and Medicare are withheld automatically from an employee’s earnings. Other deductions come in the form of benefits, which may be optional. Health, dental and vision insurance, life insurance, or a retirement fund

or we can say gross pay minus all the deductions ".

Hence, the total amount on taxes is or her total deductions: $ (72.80+34.72+8.12+30)

                                           =$ 145.64

Hence her net pay= $ 560-$145.64

                              =$ 414.36
