People are often frustrated with the amount of chips that come in a bag of chips. Or lack thereof.

For this activity, students will find out the average amount of chips found in bags of chips. They will then find the average size of a chip, and the amount of space that a chip bag can hold. From there, they will figure out how many chips could fit in bags if companies filled them up, and compare that to how many they actually put in the bag.

Example: Lays potato chips. Out of x amount of bags, they hold an average of y amount of chips, filling z% of the bag. Therefore, if they filled the bag, they could fit a amount of chips.
