A cell phone plan charges $49.95 per month plus $14.02 in taxes, plus $.40 per minute for calls beyond the 600-minute monthly limit.

Question

This question is on piece-wise functions.  I need all steps needed.

Answer 1

What exactly do you need?

 

49.95 + 14.02 = 63.97

 

c(m) = 63.97 if 0 < m ≥ 600

c(m) = 0.4m + 63.97 if m > 600
