You are trying to determine how much money the school will take in <em>before</em> giving out prize money. Knowing this, you can actually ignore the $6 that the winner will get because you are not worried about giving out the prize money yet. You are only worried about how much you will make before the prize money.

price per game * amount of people playing game = money made from games
Note: two negatives multiplied together = one positive answer one negative & one positive multiplied together = one negative answer Multiply -8 and -3 together
