First find the difference in hourly wages: $40/hour - $30/hour = $<<40-30=10>>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 = $<<10*40=400>>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 = $<<400*4=1600>>1600/month

Then find the total additional amount Janet pays in FICA taxes: $25/week * 4 weeks/month = $<<25*4=100>>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 = $<<1600-400-100=1100>>1100/month

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?
