Austin pays $1.50 per day for high speed internet after paying the equipment fee of $35.00. identify the constant of proportionality that relates her internet charges (y) to the number of days (x) he has internet.

Your constant is the $35. no matter how many days he has had internet, he will pay the down equipment fee of 35. Now your fixed variable, x is the number of days he has high speed internet. So your formula would look something like this:

y=1.50(x) + 35

y= the total internet charge
x= the number of days of internet Austin is paying for.

Hope this helps!
