Unit 5 Assignment 1: Comparing Cell Phone Plans
NAME: ____________________________________
Learning Objectives and Outcomes
Graph a linear function.
Calculate the slope of a line as specified by a linear function.
Assignment Requirements
Most cell phone carriers offer package deals in which they charge a set monthly fee and provide for a free number of anytime minutes every month. Once the anytime minutes are used up, then they charge a set rate for overage minutes. For this activity, assume you typically will use 575 minutes per month.
Research the price of cell phone plans for two different carriers. For each carrier, get prices for two different plans that are close to this assumed usage.
Create a relationship for each plan (an equation) where f(x) represents the monthly phone bill and where x represents the minutes used beyond the free anytime minutes. Remember to include the standard monthly fee in your function. Note: Give each plan a different functional name, f(x), g(x), h(x), and j(x), to distinguish them from each other.
Graph each relationship on the following graph. The x-axis will represent total minutes used, and the y-axis the total monthly cost. Note that the cost will be a horizontal line until you go beyond the free minutes.
Label each plan on the graph to match the names denoted in Step 2.
Which plan is the best one for you? Base your decision on the assumed usage.
