Figure 1.25 Statistics on sales for Gap and Amazon. Data compiled from AP [2005], Internet Retailer [2005], Gamasutra [2005], Seattle PI [2005], MSN Money [2005], Gap [2005], and Gap [2006].
c. When the site returned, the number of users allowed to visit the site at one time was limited. Imagine that it was limited to 50% of the customers who wanted to access the site. Assume that each server costs $7500 to purchase and set up. How many servers, per day, could they purchase and install with the money they are losing in sales?
d. Gap.com had 2.6 million visitors in July 2004 [AP 2005]. On average, a user views 8.4 pages per day on Gap.com.
