Question 143987This question is from textbook Elementary and intermediat algebra cenept and application
: A lawyer bills her clients $250 per hour of service. If a client's case requires 47 hours to complete, use proportion to calculate how much the client will owe the lawyer (excluding tax).
2. A new virus is released on the internet; the administrator of a department's Local Area Network ( LAN) is given five minutes by a manager to estimate the impact. The administrator samples 12 of the PCs connected to the LAN, and finds that 7 are infected; use proportion to estimate the number of infected PCs if there are a total of 117 PCs 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 web site 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 next 18 months.

You can put this solution on YOUR website! 1. $250/ 1 hour = $x/ 47 hours 250* 47= x= $11,750
2.X PCs infected/117 PCs= 7PCs infected/ 12 infected 117*7= x = 819
3.85,000 hits + 3500 * 18= 85000 + 63000= 148000 per second
X servers/ 148000 hits 1 server/ 11000
148000/11000= x = 13.45 so the administrator will need 14 new servers.
