e$ Challenge #8
I bought a book of math and logic puzzles a while back to use as challenges for another board I run. There it was for pride and fun only. Here it will be for e$500 per winning answer... first winning answer to each puzzle. Some of the puzzles are going to be actual math problems, others require logical thinking instead. I'm going to post no more than two challenges per week, and will try to post them at different times of the day in order to give folks that sign on at various different times a shot at winning the challenge. The rules:
- The answer in the book is final. Blame the publisher, not me, if you don't agree
 - The first person to post the correct answer wins. Posting only, no PM's please.
- You cannot win two challenges in a row, so the previous winner is not eligible for the next challenge.
- You may win more than one challenge, just not two in a row.
I won't post any more than one puzzle per day. That will let people argue over the answers. 
Grand Prize
The book has 100 puzzles. Each individual winner gets one lottery ticket per win. Once all 100 puzzles have been posted (and solved) I will draw three winning tickets from a hat. Each winner will get to pick one of 3 mystery portfolios. The portfolio will have an initial value of e$2000 as of the end of February, 2006. Each will be invested as completely as possible into one stock from the S&P 500 chosen at random. The winners will have no idea which portfolio is worth the most. The first person drawn will get their pick of all 3 portfolios, the second drawn picks from between the two remaining, and the third drawn gets stuck (or lucky) with the last one available. The holding will be sold at current market price as of the end of the contest and the e$ transferred into your account. Your name may be drawn more than once, so the more e$ challenges you win, the better your chances of winning one of the three portfolios.
The stocks were randomly selected and purchased at market open today. e$2000 worth of shares of each of them were put into a secret account. These will become the grand prize portfolios, and the final value will be determined at market close on the day the last puzzle is solved and the e$500 awarded.
Thanks for playing
Ready?
Here's your 7th e$ Challenge Puzzle!
We've seen this before, and INWB blew it out of the water last time. The puzzle book includes versions of this puzzle for each single digit number (meaning we have 5 through 9 to go after this.)
Same rules as before: use any combination of math symbols (+, -, *, /) including parenthesis to make each line true.
4 4 4 4 = 3
4 4 4 4 = 6
4 4 4 4 = 7
4 4 4 4 = 8
4 4 4 4 = 24
4 4 4 4 = 28
4 4 4 4 = 32
4 4 4 4 = 48
e$ Challenge Winner #1 Iceemaan
e$ Challenge Winner #2 nelaina
e$ Challenge Winner #3 conbrio
e$ Challenge Winner #4 geb9696
e$ Challenge Winner #5 CJ. Wentworth
e$ Challenge Winner #6 Im Not Warren Buffet
e$ Challenge Winner #7 CJ. Wentworth
e$ Challenge Winner #8 ???
Remember to keep things fair, the previous winner (CJ in this case) is not elegible to win the current challenge. |

| As a footnote to my last post, while I was making the winner names clickable I noticed that INWB's user_id is 1099. A nice financial number. |

That one was pretty easy
4 4 4 4 = 3
(((4*4)-4)/4)
4 4 4 4 = 6
(((4+4)/4)+4)
4 4 4 4 = 7
((4*4)-(4+4))
4 4 4 4 = 8
4*4-4-4
4 4 4 4 = 24
4*4+4+4
4 4 4 4 = 28
4*4*4-4
4 4 4 4 = 32
(4*4) + (4*4)
4 4 4 4 = 48
((4+4+4)*4)
enjoy
gah stupid mistake ;p

| I finished setting up the holdings for the prizes. Remember these were picked at random from the S&P500 list and purchased as of the market open price this morning. As of market close this evening, two stocks were up (or over) 1%, just for one day. I should be so lucky with my own picks. The third stock is down some, but we'll see where they all are when the challenges are done. |

Nope.
davef139 had everything correct but one, and didn't bother to correct it, just made the mistake bold. You have an error too. Check your math in Excel, exactly as written, and you will find the error.
For anyone that has already posted an entry that wants to change it, post a new reply to the topic, do not edit the existing reply. That way the first correct reply will be the winner. Edited posts should be disqualified... I will put that in as part of the "official rules" as of Challenge #9.
But the bottom line is, no, there is no winner. Thus, no announcement. |

The e$ Challenge portfolio stocks are, in no particular order, up 1.23%, up 2.38%, and down 0.33% so far since the start of March. The longer we take to solve all 100 puzzles the longer these stocks have to increase (or decrease  ) in value. |

(4+4)+(4-4) = 8
4*4+4+4 = 24

(4*4-4)/4=3
(4+4/4)+4=6
(4+4)-(4/4)=7
(4*4)-(4+4)=8
(4*4)+(4+4)=24
(4+4*4)-4=28
(4*4)+(4*4)=32
