So recently in math we’ve been working on systems of equations, and how to graph them. This was only a short unit and it only featured a small project. The project was to graph and find the intersect points of different phone plans for data overage charges. For this project I worked with Calum and Lucas.

The first thing we did was find 4 cell phone plans that were all different in their own ways. We got plans from Bell, Telus, Rogers, and Koodo. The Koodo plan had 10GBs of data so we treated this almost as an unlimited data plan because our graph only went out to 7GBs. We then had 2 almost identical plans with Rogers and Bell. Both of which had 3GBs of data and unlimited call. For one of the plans the overage was $7/100MBs the other was ¢7/1MB. This meant that the ¢7/1MB was a straight linear line on the graph whereas the other was all jagged. Our last plan was Telus which had 4GBs of data. If you went over your data limit it cost you $10/200MBs but only for the first GB. After that it then cost ¢10/1MB. Here is our graph:

Overall I leaned a lot from this project (especially how annoying graphing unlinear equations can be). It definetly taught me a lot about Systems of equations.
