Determine the Best Deal By Comparing Equations

This Determine the Best Deal By Comparing Equations video also includes:

Now that you've taught constant of proportionality, can your mathematicians figure out which item has a better cost based on its equation? The first video in the series introduces the constant, while this video practices using it with a situation. The three different candy cost equations are put into a table and graph to show the best deal with different amounts of candy. There is a quick review of decimals beforehand to emphasize the importance of place value.
