Media services charges $20 for a phone and $30/month for its economy plan.The equation c=30t+20 describes the total cost, c, of operating a Media Services phone for 1 month.
The total cost for 4 months of service is $30*4 + 20 = 120+20 = $140__________
If a customer has only $90 available, how many months of servie can she receive?
90 = 30t + 20
70 = 30t
t = 7/3
t = 2 1/3
3___, 2 1/3 ____, 2 1/2___, 2____.
Then, graph the equation c+30t+20 = total cost
