Question 1170573: Dinner guests are to be seated at 10 round tables labeled from A to J. Table A has 21 seats numbered consecutively from 1 to 21, table B has 22 seats numbered similarly, table C has 23 numbered seats, and so on to table J having 30 seats. At each table, starting to count at seat 1, every third person will be eliminated. Here's an example:
At a table of 12: in the first round, persons 3, 6, 9, and 12 are gone. Then, 4, 8,and 1 are eliminated. Numbers 7 and 2 are next to go. Number 11 goes next, and then 5. The winner is number 10: (The count on the last step is 5-10-5.) You have 20 seconds to choose a seat at any table from A to J. What equation can you use so that you can make a lucrative choice in 20 seconds? (x is the number of seats at a table and y is the seat that you take.)
a) y = 3x-61
b) y = 4x-83
c) y = 3x-69
d) y = 3x-57

Question 1180016: Suppose you play poker with five of your friends every week, but you’re not very good. For every week you win, there are eight weeks where you lose. You don’t play for real money though, so it’s usually no big deal. But next week your friends want to have a real game where everyone puts in $15. The winner keeps all the money, everyone else loses their $15.
a)What is the expected monetary value of playing next week?
b)Now suppose you see a book that teaches people to improve their poker game. The book costs $30, but it will increase your odds of winning.
How much would the book have to increase your odds of winning to make the expected value of buying it positive?
