Some American Colonialists still wanted to support Britain throughout the American Revolution because they considered themselves loyal to British Rule and very much still a part of Great Britain. These individuals could have worked for the British Government, done Business with the Government, or had an ideological attachment to the continuation of the colonies remaining under British control. In addition many of these individuals could have identified themselves nationally as "British" which also could have been their reason for wanting to stay a British Colony.
For the monthly fee, we first have to subtract the installation fee of 85 from the total cost for two years which is 685. Why? Because an installation fee is a one time thing. You don't install every year. So less the installation fee, our internet service cost for two years is 600. To make things easier, lets get the service costs for one year. Divide 600 by 2 and you will get 300. 300 is the cost of the internet for a whole year. Divide this by 12 (12 months in a year) and you will get 25. The monthly cost is $25.
