Q: A firefighter is paid $30 per hour for a 48-hour workweek. He pays 1/3 of the money on rent and $500 on food and $1000 on taxes per month. Calculate the total amount of money the firefighter has after paying his monthly expenses.
A: The firefighter earns $30 / hour * 48 hours / week = $1440 in a week. In a month, the firefighter earns $1440 / week * 4 weeks / month = $5760. His total monthly payment is 1 / 3 * $5760 = $1920. His total monthly expenses are $1920 for rent + $500 for food + $1000 for taxes = $3420. The total amount of money the firefighter has after his expenses is $5760 - $3420 = $2340. The answer is 2340.
