Two cell phone companies have different rate plans. Runfast has monthly charges $10 plus $4 per gig of data. B A &D’s monthl
y charge is $6 plus $6 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. (1pt) Determine the equation for the monthly charges for Runfast and B A&D.
Runfast= ______________________
BA&D=________________________
2. (4 pts)Use your mathematical skill to solve this system of equations using the substitution method. (show your work here)
Both companies will cost the same if you use 2 Gb of data. BA&D will be cheaper if you use less than 2 Gb of data. Runfast will be cheaper if you use more than 2 Gb of data.
