When you are making a prediction, it is important to be able to recognize whether a relationship is proportional or not.

• Your Task: Work with your team to read each new situation below.  Decide whether you think the relationship described is proportional or non-proportional and justify your reasoning.  Be prepared to share your decisions and justifications with the class.  (From 4.2.1 #4-27)
  
1. Carlos wants to buy some new video games.  Each game he buys costs him $36.  Is the relationship between the number of games Carlos buys and the total price proportional?
