This document discusses inequalities in mathematics and provides an example of using an inequality to solve a word problem about purchasing gummy bears. It explains that the mathematical symbol I<3U does not mean "I love you" but rather means "I am less than 3 of you." It then presents a word problem where a person has $20 to spend on gummy bears that cost $0.30 per ounce and uses an inequality to determine that the person can purchase less than 4.16 pounds of gummy bears without spending all their money.
