An inequality is a mathematical statement that compares two quantities and uses symbols such as ">" (greater than), "<" (less than), ">=" (greater than or equal to), "<=" (less than or equal to), or "!=" (not equal to). In this case, we can represent the requirement for riding the roller coaster using an inequality.
Let's assign "h" as the variable representing a person's height in inches. The inequality representing the requirement for riding the roller coaster would be:
h > 48
This inequality states that a person's height, denoted by "h", must be greater than 48 inches in order to ride the roller coaster.
