Well I got 4 cards for a card that is worth about 6 brains.

6 brains divided among 4 cards is equal to 1.5 brains (which in this case is rounded up to 2 brains for maximum profit)

Since I live in Minnesota, the taxes here are 7.5%, therefore I must charge 2.015 brains. Since you cannot divide a brain, I would take an R or rarer card to make up for that .015 brain that I need :)
