The smallest pack possible includes one cheese cracker snack and one juice box:
The red ovals represent snack packs. Since there are not enough cheese cracker packs to make 77 snack packs, the maximum amount of packs that can be made is 76.
From the drawing, we can see that each snack pack will have one juice box.
