Question 1206583: It is given that in less than 60 mins, the cost function is 30, and above 60 min the charge is (x-60) more than the base plan, and an additional 0.30$ have been paid for every (x-60) minute.
Therefore, the cost function for both conditions is as follows.
Now, to keep the bill less than or equal to $50, the cost function 30+0.50(x-60) should be used.
C(x)=20,60c(x)=20+0.30(-60),>60
