Well i atleast know its not 10 lol
Let n = number of months both have their services
Provider A:
C = 35.50n + 55
Provider B:
B = 35.50n
Provider A will always cost more than
provider B because of the $55 installation fee
Make a table based on the graph and then do y=mx+b
0.98, 0.34, 0.27
pretend the zeors/decimals arent there and its the same thing, just remember to out the zeros back in when you write down your final answer
