Janet is trying to decide whether to quit her job and start freelancing. She works 40 hours a week at both jobs. She get paid $30/hour at her current job, and would get paid $40/hour as a freelancer. However, she'd have to pay an extra $25 a week in FICA taxes plus $400/month in healthcare premiums. How much more would Janet make per month as a freelancer if there are four weeks in a month?
First find the difference in hourly wages: $40/hour - $30/hour = $
<gadget id="calculator">40-30</gadget>
<output>10</output>
10/hour.
Then multiply that difference by the number of hours she works in a week to find the weekly difference: $10/hour * 40 hours/week = $
<gadget id="calculator">10*40</gadget>
<output>400</output>
400/week.
Then multiply that amount by the number of weeks in a month to find the monthly difference in her earnings: $400/week * 4 weeks/month = $
<gadget id="calculator">400*4</gadget>
<output>1_600</output>
1600/month.
Then find the total additional amount Janet pays in FICA taxes: $25/week * 4 weeks/month = $
<gadget id="calculator">25*4</gadget>
<output>100</output>
100/month.
Then subtract Janet's extra FICA taxes and healthcare premium from the additional money she earns to find the net increase in her pay from freelancing: $1600/month - $400/month - $100/month = $
<gadget id="calculator">1600-400-100</gadget>
<output>1_100</output>
1100/month.
