Understanding Inequalities: Finding Multiple Solutions using a Number Line

The video tutorial explains how inequalities can have multiple solutions, using a number line to demonstrate this concept. It introduces the symbols for inequalities and applies them to a real-world problem involving a field trip budget. The tutorial uses substitution to test possible solutions and addresses common misunderstandings, emphasizing that solutions are not limited to whole numbers and can include any rational number greater than the specified value.
