Question: Phoebe eats 1 serving and gives her dog 1 serving of peanut butter for a bedtime snack. Each jar of peanut butter has 15 servings. How many jars will she need to make sure she and her dog have enough to last for 30 days?
Answer: She and her dog both have a serving before bed so they eat 1 + 1 = 2 servings a day. She wants to have enough for 30 days and they eat 2 servings a day so they need 30 * 2 = 60 servings. Each jar has 15 servings and she needs 60 servings so she will need 60 / 15 = 4 jars of peanut butter. The answer is 4.

Q: Bert, Ernie, and Peggy collect stamps. Bert has four times as many stamps as Ernie, but Ernie has three times as many stamps as Peggy. If Peggy currently has 75 stamps in her collection, how many stamps does she need to add to her collection to have a collection as large as Bert's collection?
A: Ernie has three times as many stamps as Peggy, or 3 * 75 = 225 stamps. Bert has 4 times as many stamps as Ernie, or 4 * 225 = 900 stamps. Thus, Peggy would need 900 - 75 = 825 more stamps to have a collection as large as Bert's. The answer is 825.
