Brian and his friend Tom had a lemonade stand. They spent $40 on supplies. They sold $160 of lemonade in 5 hours. If the boys split the money left over evenly, how much money did Brian make each hour?
A. $8
B. $10
C. $12
D. $24
C - 160 -40 = $120 (the amount of money left over). One way to get the answer: 120/5 = $24 made each hour by both boys together. Because there are 2 boys, 24/2 = $12, the amount each boy made each hour. Another way: 120/2 = $60 for each boy, $60/5 hours = $12 per hour.
