posted by student .
A cable tv company charges $50 for the basic service plus $10 for each movie channe. Let C(X) be the total cost in dollars of subcribing to cable tv, using x movie channels. write a cost function for the problem.
what i think it is:
c(x)= 50 + 10x
That looks ok to me.

C (x)=50+10x
