Q: Jack needs to put his shoes on, then help both his toddlers tie their shoes. If it takes Jack 4 minutes to put his shoes on, and three minutes longer to help each toddler with their shoes, how long does it take them to get ready?
A: First figure out how long it takes to help one toddler: 4 minutes + 3 minutes = 7 minutes. Then multiply the time per toddler by the number of toddlers: 7 minutes / toddler * 2 toddlers = 14 minutes. Now add the time spent helping the toddlers to the time Jack spends on his own shoes: 14 minutes + 4 minutes = 18 minutes. The answer is 18.
Question: Charles is wondering how much chocolate milk he can make with all the supplies he finds in the fridge. He is going to keep drinking 8-ounce glasses until he uses up all the ingredients. Each glass must contain 6.5 ounces of milk and 1.5 ounces of chocolate syrup. If he has 130 ounces of milk and 60 ounces of chocolate syrup, how many total ounces ounce of chocolate milk will he drink?
Answer: He has enough milk for 20 glasses of chocolate milk because 130 / 6.5 = 20. He has enough syrup for 40 glasses of chocolate milk because 60 / 1.5 = 40. He can make 20 glasses of chocolate milk because 20 < 40. He will drink 160 ounces of chocolate milk because 20 x 8 = 160. The answer is 160.
[Question]James paints a 20 ft by 15 ft mural. It takes him 20 minutes to paint 1 square foot and he charges $150 per hour. How much does he charge to paint the mural?
[Answer]The mural is 20 * 15 = 300 square feet. So it takes him 300 * 20 = 6000 minutes. So he paints it in 6000 / 60 = 100 hours. That means he charges 100 * 150 = $15000. The answer is 15000.

Answer: He bought 12 - 3 - 2 = 7 blue notebooks. He paid 3 * $4 = $12 for red notebooks. He paid 2 * $2 = $4 for green notebooks. He spent $37 - $12 - $4 = $21 on blue notebooks. Each blue notebook costs $21 / 7 = $3. The answer is 3.
Q: There are 10 students in a class. The average age of 9 of them is 8 years. By how many years will this average increase if the tenth student is (quite strangely) 28 years old?
A:
9 students have an average age of 8 years so the sum of their ages is 9 * 8 = 72 years. A tenth student who is 28 years old will make the sum 72 + 28 = 100 years. The new average age will be 100 / 10 = 10 years. This is 10 - 8 = 2 years higher than the previous average. The answer is 2.
