is there anymore data? Or are you suppose to make up your own pricing?

Let:
x=number of minutes
y= monthly bill
Made up information:
AT&T charges $15 as a flat fee and 10cents per minute
y=15+0.10x
Verizon charges $18 flat fee and 5cents per minute
y=18+0.05x
Set both equation equal to each other:
15+0.10=18+.05x
x=60mins
Now we know that at 60mins, both the company's monthly bill will be the same
If x > 60, Verizon is cheaper
Plug in whatever value you want for x to find out.
