The administrator samples 12 of the PC's connected to the LAN, and finds that 7 are infected; use proportion to estimate the number of infected PC's if there are a total of 117 PC's connected to the LAN.

3. An administrator of a popular web site is told that a new server can handle 11,000 "hits" (users accessing the site) per second. The website currently experiences a peak demand of about 85,000 hits per second; but every month, the peak demand increases by 3500 hits per second. Use a proportion equation to determine how many new servers the administrator should buy to address expected traffic for the site.
