Determining the Best Deal: Comparing Equations for Proportional Relationships

In this video, students learn how to determine the best deal by comparing equations that represent the proportional relationship between the total cost and the number of items. They are taught to find the unit cost by dividing the total cost by the total number of items, and to use the unit cost to determine the best deal. The video also explains how to extrapolate data for multiple items and how to graph the cost based on the number of items. Overall, it provides a comprehensive understanding of comparing deals and making informed decisions.
