Diagonally is fine, sorry for the late answer.
The answer 88 is incorrect.  Contest is still open. |

Ding ding ding! We have a winnah! 
Here is the description from the book:
We select the place of the first O:
- At the center, it touches 4 S's, each touching 3 L's, each touching 3 O's, which yields 36 words
- At the corners, no words
- At the sides: each of the 8 O's touches 1 S, touching 3 L's, each touching 3 O's, which yields 72 words.
In all, there are 108 words. |

e$ Challenge #55
Compete for e$5000! (The prize amount was increased starting with e$ Challenge #15, and then again to e$5,000 with #52.) Solve the puzzle and win! ... first winning answer to each puzzle. Some of the puzzles are going to be actual math problems, others require logical thinking instead. Each puzzle comes from a book I bought a while back. 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.
- Edited posts are disqualified, even if you have the correct answer. The most recent (last) post by you for that puzzle is the only one that will be used, so if you need to make corrections simply enter another post for the challenge.
- 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 will try to post one puzzle every other day. The puzzle will be posted first, then the following day (if available) a winner will be announced. Then the arguments or discussion about the solution can commence.  If no correct solution has been provided then the puzzle will be extended until a winning solution is provided. The puzzles get more challenging as we get further into the book.
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$2000 as of the end of February, 2006. Each has been invested as completely as possible into one stock from the S&P 500 chosen at random. The winners will have no idea which portfolio is worth the most. The first person drawn will get their pick of all 3 portfolios, the second drawn picks from between the two remaining, and the third drawn gets stuck (or lucky) with the last one available. The holding will be sold at current market price as of the end of the contest and the e$ 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 March 1, 2006. e$2000 worth of shares of each of them were put into a secret account. These will become the grand prize portfolios, and the final value will be determined at market close on the day the last puzzle is solved and the e$ prize awarded.
Thanks for playing
Ready?
Here's your 55th e$ Challenge Puzzle! Benjamin is having dinner with a friend. Benjamin brought five dishes and his friend brought three dishes. (sounds like take-out food to me)
At the last minute, JRW-910 comes and eats with them.
JRW-910 pays $4 as his share. If all of the dishes have the same value, how can the money be divided between Benjamin and his first friend so each gets paid an equitable share?

That is the most common incorrect answer. You are on the right track but are missing an important aspect of the puzzle. |

Assuming each person had 1/3 of the dishes:
JRW-910 paid $4, so the total cost of the meal is $12.
Benjamin brought $7.50 worth of food ($12 * 5/
Benjamin ate $4 worth of food.
Benjamin should get $3.50 back. |

Hm. A bit of a quandry. prederer has the correct logic but an incomplete answer. MrT provided the complete answer, but didn't show any work, and the answer came several hours later. Given that the prizes have been increased to e$5,000 for each puzzle, I think that I am going to solve this by splitting the award money between both.
Since prederer wrote a detailed explanation for the answer (and answered first) but did not complete the answer (did not say where all of the $4 was to go, only that Benjamin got $3.50) and since MrT didn't provide any justification but did offer a complete answer, and since I like a certain amount of symmetry, I will award prederer with e$3,500 and MrT with e$500 to match the ratio of the $4 split from the puzzle. That leaves e$1000 remaining, which I will split equally.
So prederer will be awarded e$4,000 while MrT will be awarded e$1000 for his later less-detailed but complete response. |

| Haha, I like your logic. I only answered because I didn't think he had a complete answer before. |
