[Call me when humans go extinct]

Make a system for X ; Y ; Z to get you this--->
X: Money paid $/€
Y: Hours you get from dealing with your internet provider (h)
Z: Internet speed measurment that you're surfing for the proportionality of its use

By making this system and getting the right number for x , y , z , you have to make Delta for it and divide your x into 2 parts. So calculating the "derivée" of x and Expotatienl primitive of z.

Here you can know how much you're ISP works for C++ on your own surfing rules approx.

didnt know you do programming. >.>
