Inequalities and Luisa's Bouquets

The video tutorial covers inequalities, explaining the symbols used to compare quantities. It provides examples of solving inequalities, including real-world applications like determining when Luisa receives a bonus based on her flower bouquet sales. The tutorial emphasizes understanding when a given value is a solution to an inequality.
