14. cable bill your local cable company charges $29.99 per month for basic cable service. premium channels are available for a surcharge of $5.95 per channel. you have $70 per month budgeted for cable. how many premium channels can you purchase?
Answer
Explanation:
Step1: Subtract basic - cable cost
First, subtract the cost of basic cable from the budget. $70 - 29.99=40.01$.
Step2: Divide by per - channel surcharge
Then, divide the remaining amount by the surcharge per premium channel. Let $n$ be the number of premium channels. $n=\frac{40.01}{5.95}\approx6.725$. Since we can't have a fraction of a channel, we take the whole - number part.
