Question

The local cable company charges $90 per month for basic and $12 per month for each additional premium cable channel.The function c(x)=90x+12x represents the monthly charge (in dollars),where x represents the number of additional premium channels.How many additional premium channels would you have ordered if your bill wad $114 per month?

Answer 1

Answer:

2 additional premium channels

Step-by-step explanation:

Using the given function, we substitute c(x) = 114 and solve for x:

114 =90 + 12x

Subtract 90 from both sides:

24=12x

Divide both sides by 12:

2=x

So you have ordered 2 additional premium channels.
