Final answer:
To calculate Lindsey's net pay, subtract the deductions and taxes from her gross earnings: $840 - $50.40 - $12.60 - $151.20 = $625.80.
Step-by-step explanation:
To calculate Lindsey's net pay, we need to subtract the deductions and taxes from her gross earnings. The social security tax rate is 6%, so the amount deducted for social security tax is 0.06 * $840 = $50.40.
The Medicare tax rate is 1.5%, so the amount deducted for Medicare tax is 0.015 * $840 = $12.60.
Additionally, her federal income tax withholding is already given as $151.20.
To find Lindsey's net pay, we subtract the deductions and taxes from her gross earnings:
Net Pay = Gross Earnings - Social Security Tax - Medicare Tax - Federal Income Tax Withholding
Net Pay = $840 - $50.40 - $12.60 - $151.20 = $625.80
Therefore, Lindsey's net pay is $625.80.
