In a car dealership, Fiona worked for 40 hours a week, John for 30 hours, and Jeremy for 25 hours. If the employees are paid $20 per hour, how much money does their boss spend paying all of them every month? Think carefully first, then make a decision:
Fiona earns 40 hours / week * $20 / hour = $800 / week. So she earns $800 / week * 4 weeks / month = $3200 / month. John earns 30 hours / week * $20 / hour = $600 / week. So he earns $600 / week * 4 weeks / month = $2400 / month. Jeremy earns 25 hours * $20 / hour = $500 / week. So he earns $500 / week * 4 weeks / month = $2000 / month. Overall their boss has to spend $3200 / month + $2400 / month + $2000 / month = $7600 / month. So, the answer is 7600.
