Calvin currently has 125 empty juice boxes and wishes to recycle them at the supermarket to get full juice boxes. What is the maximum number of full juice boxes Calvin can drink by recycling empty juice boxes?

First, Calvin recycles all 125 of his empty juice boxes to get 25 full juice boxes. Then, after Calvin drinks them all, he is left with 25 empty juice boxes that he can trade in to get 5 more juice boxes. Finally, after finishing those, he can trade in the 5 empty boxes to get 1 full box. Thus, Calvin can get a maximum of 2 5 + 5 + 1 = 3 1 juice boxes through the recycling program.
