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!
Determine the equation for the monthly charges for Runfast and BA&D.
Runfast= $35 per month
BA&D= $33 per month   Can you help me with the graphing? I have everything else
