so you want to solve
6g + 6 = 4g + 10
2g = 4
g = 2
So at 2 G, the cost is the same for both, namely $18
Two cell phone companies have different rate plans. Runfast has monthly charges $10 plus $4 per gig of data. B A &D’s monthly 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.
(1pt) Determine the equation for the monthly charges for Runfast and B A&D.
Runfast = 4g+10
BA&D = 6g+6
(4 pts)Use your mathematical skill to solve this system of equations using the substitution method, not just picking numbers to see what fits. (show your work here)
I already got the first one, I just don't know how to do the second, please help!
