Peyton has 3 children and they each get a juice box in their lunch, 5 days a week. The school year is 25 weeks long. How many juices boxes will she need for the entire school year for all of her children? Let's answer step by step:
Each of the 3 children gets 1 juice box, 5 days a week, so she needs 3 * 5 = 15 juice boxes in 1 week. The school year is 25 weeks long and she needs 15 juice boxes per week so she needs 25 * 15 = 375 juice boxes. The answer: 375.
