Option d. $623.52

Step-by-step explanation:

Lauren has gross pay = $765

social security tax = 6.2% and medicare tax = 1.45%

= 6.2 + 1.45 = 7.65% of $765

× 765

= 0.0765 × 765

= 58.52

Social security tax and medicare tax withholding = $58.52

State tax = 22% of her federal tax

= 22% × $68

= 0.22 × 68

= $14.96

State tax withholding = $14.96

Federal tax withholding = $68

Her net pay = $765 - 58.52 - 14.96 - 68

                    = $623.52

Option d. $623.52
