Question 936320: Please help me solve this problem: A cable company charges $39.95 per month for basic cable service and $8.95 per month for each premium channel. If Derek's monthly bill is $66.80, how many premium channels does he receive?
Answer by TimothyLamb(4379) About Me  (Show Source):
You can put this solution on YOUR website!
x = number of premium channels
y = total cost
---
y = 8.95x + 39.95
---
66.80 = 8.95x + 39.95
8.95x = 66.80 - 39.95
x = (66.80 - 39.95)/8.95
x = 3
