Q: Eden's mom is twice as old as Eden, who is twice as old as Devin. If Devin is 12 years old, what's the average age of the three?
A: If Devin is 12 years old, then Eden is 2 * 12 years = 24 years old. Since Eden's mom two times older than Eden, her age is 24 years * 2 = 48 years. In total, they have 48 years + 24 years + 12 years = 84 years. The average age for the three is 84 years / 3 people = 28 years / person. The answer is 28.

[Question]To eat to when she gets full, Michaela needs 20 oranges. Cassandra needs twice as many oranges as Michaela to eat until she gets full. If they picked 90 oranges from the farm today, how many oranges would remain after they've both eaten until they were full?
[Answer]Since Michaela needs 20 oranges to eat to her full, and Cassandra eats twice as much to have her full, Cassandra needs 2 * 20 = 40 oranges to eat. They eat 20 + 40 = 60 oranges together to have their fill. If they picked 90 oranges today, after eating 60 together, 90 - 60 = 30 oranges would remain. The answer is 30.
Q: Andy started out the year weighing 156 pounds. He then grew 3 inches and gained 36 pounds. Andy wasn't happy with his weight and decided to exercise. Over the next 3 months, he lost an eighth of his weight every month. How much less does Andy weigh now than at the beginning of the year?
A: Andy weighed 156 + 36 = 192 pounds after growing taller. An eighth of his weight is 1 / 8 x 192 = 24 pounds. Over the next 3 months, Andy lost 24 x 3 = 72 pounds. He now weighs 192 - 72 = 120 pounds. Andy weighs 156 - 120 = 36 pounds less than at the beginning of the year. The answer is 36.

Q: An Italian restaurant earns $600 every weekday and twice as much on the weekend. How much money does it earn by the end of the month?
A:
On weekdays it earns $600 / weekday * 5 weekdays = $3000. During the weekend it earns twice as much each day so it makes ($600 * 2) / weekend day * 2 weekend days = $2400. Every week it earns $3000 + $2400 = $5400. By the end of the month, it earns $5400 / week * 4 weeks = $21600. The answer is 21600.
