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?
Each of the 3 children gets 1 juice box, 5 days a week, so she needs 3*5 = <<3*5=15>>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 = <<25*15=375>>375 juice boxes
#### 375
