1) How many possible ways could a list of n values be ordered, i. e., how many ordering permutations are there? 2) Argue that if you know a list’s order permutation, sorting is easy (linear time), and conversely, if you know the steps to sort the list, you can easily generate the order permutation. 3) Given this, argue that sorting can’t be easier than finding the order permutation.

James wants to promote his band on the internet. site a offers website hosting for $4.95 per month with a $49.95 startup fee. site b offers website hosting for $9.95 per month with no startup fee. for how many months would james need to keep the website for site a to be a better choice than site b? 1. define a variable for the situation. 2. write an inequality that represents the situation. 3.solve the inequality to find out how many months he needs to keep the website for site a to be less expensive than site b. 4. using words, describe how many months he needs to keep the website for site a to be less expensive than site b.
