Problema Solution
The number of Internet users I in millions during year x, where x is equal to or greater than 2000, can be approximated by the following formula.
I=108x-215,445
Approximate the year in which there were 1090 million Internet users for the first time. (Round to the nearest year)
Answer provided by our tutors
I = 108X - 215445
Given I=1090 million users
1090 = 108X - 215445
=>1090+215445=108X
=>216535=108X
=>X=216535/108
=>X= 2004.9 ~ 2005 year
