The chess clubs of two schools consist of, respectively, 8 and 9 players. Four members from each club are randomly chosen to participate in a contest between the two schools. The chosen players from one team are then randomly paired with those from the other team, and each pairing plays a game of chess. Suppose that Rebecca and her sister Elise are on the chess clubs at different schools. What is the probability that (a) Rebecca and Elise will be paired?

You can set up 2 equations for the two companies that sell pizza. Pizza A's will be:
And B's will be:
To find the number of toppings we will need to make the companies prices equal can be found by setting the equations equal to each other and solving for x, because x is the price per topping. So:
So, the number of toppings you will need is 5 toppings to make their prices equal.
