One computer industry expert reported that there were about 600 million computers in use worldwide in 2001 and that the number was increasing at an annual rate of about 10%. How many computers would there have been worldwide in 2009?

Given that a computer industry expert reported that there were about 600 million computers in use worldwide in 2001 and that the number was increasing at an annual rate of about 10%, to determine how many computers would there have been worldwide in 2009, the following calculation must be done:

2002 = 600 x 1.1 = 660

2003 = 660 x 1.1 = 726

2004 = 726 x 1.1 = 798.6

2005 = 798.6 x 1.1 = 878.46

2006 = 878.46 x 1.1 = 966.306

2007 = 966.3 x 1.1 = 1,062.9366

2008 = 1,062.93 x 1.1 = 1,169.23026

2009 = 1,169.23026 x 1.1 = 1,286.153286

1,286.153286 x 1,000,000 = 1,286,153,286

Thus, in 2009 there would be 1,286,153,286 computers.
