close. You forgot the first piece
y = 40 when 0 <= x <= 500
y = 40+.05x when x > 500
I guess we can assume that negative minutes are to be disregarded as a possibility.
a cell phone company offers the following plan: monthly charge (which includes 500 minutes) for $40 and a charge for additional minutes will be 5 cents a minute. write a piecewise function function putting x&y terms that can be used in any # or minutes.
I am coming up with y=.05x+40 when x>500. Although I'm not sure.
