Determining the Best Deal: Comparing Equations for Proportional Relationships

This video tutorial explains how to determine the best deal by comparing equations that represent proportional relationships between total cost and the number of items. It covers the concept of unit cost, how to calculate it, and how to write equations for proportional relationships. The tutorial also includes a comparison of unit costs using a candy example and demonstrates how to graph data to visualize these relationships.
