Question
Two cell phone companies have different rate plans.Runfast has monthly charges $25 plus $10 per gig of data.B A&D’s monthly charge is $18 plus 15 per gig of data. Your task is to determine under what circumstances each company has the better pricing. You will derive and solve a set of equations, graph those equations, and evaluate the meanings for these events. Don’t worry; I have a series of questions to guide you through the process. Good luck!
1. Determine the equation for the monthly charges for Runfast and B A&D.
Runfast= ______________________
BA&D=________________________
2. Use your mathematical skill to solve this system of equations using the substitution method. (Show your work here.)
3. Graph the results on the accompanying graph as a visual aid. Don’t forget to label which line is for which company.
4. Why don’t the lines start at the origin?_______________________________________________
5. What is special about each of the y-intercepts?________________________________________
6. Which company has the better deal for customers that don’t us much data? How do you know?__________________________________________________________________________________________
7. At what point are the plans the same amount? How do you know?____________________________
8. Which company has the better deal for customers that use a lot of data? How do you know?_______________________________________________

what, can you not answer any of the guiding questions?
I'll do #1
For x GB of data, the costs are
Runfast: 25+10x
BA&D: 18+15x
now crank it out

Hey ya'll! Just as a warning absolutely do not use Steve's answer for the first question. It would be right if we were graphing linear equations but we aren't! It's also a dead giveaway that you tried to cheat! Your best bet is to watch the portfolio recording and substitute jane and tammi's numbers for Runfast and BA& D's numbers. It's really simple! Good Luck and Good working guys!
