Answer:
It would cost $39.95 in a month when you use the internet for 14 hours.
Explanation:
Suppose, the internet is used for
hours and the monthly total cost is
dollars.
The internet company charges $4.95 per month plus $2.50 for each hour of use.
That means, fixed cost is $4.95 per month and the cost for
hours of use

So, the linear equation in slope intercept form to model the situation will be:

Now, if
hours, then

So, it would cost $39.95 in a month when you use the internet for 14 hours.
