What Can I Afford?
In this lesson, students will explore the various costs of cell phone plans based on a vignette that appears in the show ""TV411,"" Episode #122. The rate structures of cell phone plans represent linear functions students will graph in order to determine which plan would result in the greatest savings. Then, students will use these skills to compare checking account options to find the one that best suits their needs. The lesson plan concludes with students comparing various types of banking accounts to determine which one would yield the highest returns, if the money saved from the cell phones were placed in different accounts.
