Proportional Relationship with a Table and an Equation

The video tutorial explains proportional relationships using tables and equations. It begins with an introduction to the concept, followed by a two-part question. Part A involves calculating the total cost of seven boxes of cookies using a given table, identifying the unit rate as $3.50 per box. Part B focuses on formulating an equation to determine the total cost for any number of boxes, represented as C = 3.50 * N. The tutorial emphasizes understanding the relationship between the number of boxes and the total cost, using both tabular data and algebraic equations.
