Zapping Zombies
Leo likes playing a video game where he has to zap zombies and turn them into statues before they invade a town. In the game, zombies hide everywhere. Leo’s goal is to clear all the zombies to make the town safe.
To advance to the next level he has to zap all the zombies in the level. Each level has the same number of zombies and the same number of points is earned for each zapped zombie. As players move through the levels the zombies get harder to zap.
Leo made the table below to show a relationship between the total number of zombies zapped and the number of points.
