Comparing Mobile Phone Chargers

Added: 26 Jun 2019 Contributor: PDST Resource type: Experiment / Guide/notes

Use this interactive file to understand how graphs can be used to compare charges of different phone networks. Learn the effect that a fixed charge and a per-minute charge have on the overall cost. Use in conjunction with the corresponding student activity. Drag the sliders to change the fixed charge and the cost-per-minute of a phonecall for Network A and Network B. Drag the red dot to find the total cost of a phone bill as the number of minutes increases.
