Answer: 16 boxes and 6 football cards in each box.

Step-by-step explanation:

And, He filled 9 boxes with basketball cards.

Also, Rob filled 3 fewer plastic boxes with football cards than basketball cards.

Therefore, football cards in each boxes = 9 - 3 = 6

Thus, the number of boxes he can fill with football cards = 96/6 =16
