Answer:

28 dollars, Christen sell 7 boxes and Rafael sell 4 boxes.

Step-by-step explanation:

We can make a list to see the rate of amount and dollars they got:

Boxes:     1,    2,  3,  4,   5,    6,    7,   8

Christen: 4,   8, 12, 16, 20, 24, 28, 32  ($)

Rafael:     7, 14,  21, 28, 35, 42, 49, 56 ($)

So the first one in common is 28 dollars, and just match them to the boxes, that's it.
