We are given the following in the question:
Number of people using the internet =
[tex]5.8078 \times 10^8[/tex]
Number of people in United States =
[tex]1.6575 \times 10^8[/tex]
Percent of Internet users in 2003 were in the United States =
[tex]=\dfrac{\text{Number of users in United States}}{\text{Number of internet user in world}}\times 100\%\\\\=\dfrac{ 1.6575 \times 10^8}{5.8078 \times 10^8}\times 100\%\\\\=28.5\%[/tex]
