A: y = .60 + .02x
B: y = .045x
I guess you can take it from there, eh?
A calling card offers two methods of paying for a phone call. Method A charges $0.02 per minute but has a $0.6 connection fee. Method B charges $0.045 per minute but has no connection fee. Write the equations that show the total cost, y, of a call of x minutes for methods A and B and determine their intersection point. What does the intersection point represent?
The equation representing Method A is y =
