Question

Two years of local internet service costs $685, including the installation fee of $85. what is the monthly fee?

Answer 1

With this problem, we need to set up an equation that involves a variable and a constant. The monthly fee is going to be the variable, since the price of the service will change depending on how many months you have the internet. Since the fee is monthly, we need to change our years into months (24 months). Let's say our variable is "x". Now, when installing the internet, we pay a flat $85 fee. So, that is our constant. The total will equal $685. This will give us the equation: 

 

24 x + $85 = $685 , where x equals the monthly fee. Now all you have to do is solve for x. If you are interested in seeking tutoring sessions for math, you can find me on Wyzant! My fee is very affordable and I would love to work with you!
