Writing Inequalities from Real-World Scenarios

The video tutorial explains how to write inequalities to represent real-world situations. It covers two examples: the minimum age requirement for driving and the height requirement for riding a roller coaster. The tutorial highlights key terms like 'at least' and 'more than' to determine the appropriate inequality symbols. It also provides practice problems for viewers to apply their understanding.
