You can put this solution on YOUR website! There are 4 weeks in a month, and most people work 5 days/week
and 40 hours/day days/month of work
Let = monthly pay in dollars
(x/1 month ) x (1 month/4 weeks) x (1 week/5 days) x (1 day/40 hours) = x/(4 x 5 x 40) = x/800
Hourly, you earn (monthly pay)/800
If you earned $4,000/month, you make = $5/hr
