Phone Plans

Challenge
As the owner of a new phone store, you will design a talk and a text plan to earn as much money as possible. Raising the price of the plan may increase the amount of money you earn, but it may also decrease the number of people who sign up. Once you set the amounts for your plan, you will have the opportunity to see how much money you made. Then you will analyze the data from your plan, decide what changes you can make to increase the amount of money you earn, and try again.

Fun Facts

Cell phone companies offer many plans with different amounts of included minutes and messages, different base prices, and different costs for going over the number of included minutes and messages. Companies carefully design their plans to earn the most amount of money, not necessarily the most number of customers. To do this, they analyze data from cell phone users and calculate averages to find a single value that is typical for different groups of customers. They also use linear functions to represent the relationships between the base price, included minutes, and overage rate to help decide how to set the amounts for each plan.
