John rents his car out 10 times a month for 3 hours each time. He gets paid $25 an hour. If his car payment is $500, how much profit does he make on his car?

How many hours does he rent his car out in a month? ** He rents his car 10*3=<<10*3=30>>30 hour a month
How much money does he make in a month? ** So he makes 25*30=$<<25*30=750>>750 a month
How much profit does he make on his car? ** That means he has a profit of 750-500=$<<750-500=250>>250 a month
