Text Messaging and Commission Problems

The video tutorial covers two main problems from lesson 20. The first problem involves comparing commission rates between two security system companies using graphs to determine which company offers a better rate. The second problem involves comparing the number of text messages sent by two sisters to determine who sends more messages per week. The tutorial emphasizes understanding unit rates, using graphs, and applying equations to solve real-world problems.
