Media services charges $40 for a phone and $30/month for its economy plan.
Find a model that determines the total cost C(t) of operating a media services phone for t months.
C(t)= 30t+40 This is as far as I got.
Use the model to find the total cost for 10 months of service. Total cost =$
:
Just substitute 10 for t
C(t) = 30(10) + 40
C(t) = 300 + 40
C(t) = $240
