Our new math project “Cell Phone Systems” we continued to work with linear equations by calculating which cell phone plans are the cheapest for data roaming. I was in a group with Lucas and we quickly picked out our three sources with Bell, Telus and Rogers. They were all charging different prices for base rates with add ones later if you chose to use them. 

The first thing we had to do was get them into equations so that we could make our graphs. The three equations were Y= 1.45x + 1275 for bell, Y= 1.40x + 1415 for Telus and Y= 2x + 1200  for Rogers.

The equations follow the y=mx+b formula with B being the intercept and MX being the slope. After plotting our pints we made a chart like this:  

As you can see at the start Rogers is the cheapest but as the usage goes up so do their prices and Telus becomes cheaper overtime Rogers falling behind and bell staying somewhat in the middle. 

For our presentation Lukas made a rap that I edited into a video where he talks about everything I just went over except line intercepts and algebraic solving. 

I’ll mention that here even though we didn’t use algebraic solving in our project. So here’s a photo explaining how we would use it.

This was a very short project which didn’t make it very memorable but I still thought it was pretty enjoyable nevertheless.
