Lizzy: 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?.
Me: Hmmm, let me think. I think this is the detailed solution:

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. Final answer: 36.
