The number of internet users I in millions during year x, where x is > or = 2000 can be approximated by the following formula: I = 117x-233,479

Approximate the year in which there were 1090 million Internet users for the first time. It was in the year?

1090=117x-233479.

1090+233479=117x.

234569 =117x.

x=234569/117

2004.86 or say 2005.

=2005.

In 2005  1090 million Internet users f will be there.
