If it was tomorrow here now, then maybe then.

Re: Please Help me with this puzzle.

Well, I woke up this morning (waaaay too early) and sure enough, it's tomorrow now (although it still feels like yesterday).

But the possibility of petrichor being the source of my affluence is definitely out because we're in the grip of quite a cold start to winter here, and on average this month it has rained every other day.

Back to bed...

Re: Please Help me with this puzzle.

That's most unlikely (see here.) And if chlorophyll instead of sugar had been put into my tea I would've noticed (which I didn't).

Re: Please Help me with this puzzle.

My affluence is long gone, thanks (spent, one might also say)...'twas just a momentary hiccup.

hiccup: c.f. hiccough...

OED:

Hickop, hiccup, appears, from its date, to be a variation of the earlier hickock, hicket. Hiccough was a later spelling, apparently under the erroneous impression that the second syllable was cough, which has not affected the received pronunciation, and ought to be abandoned as a mere error.

Chambers:

The spelling hiccough is due to an earlier confusion with cough.

Merriam-Webster:

hiccough by folk etymology (inluence of cough).

Fowler's:

The spelling -ough is a perversion of popular etymology, and 'should be abandoned as a mere error'—OED.

Also, re hiccuping, hiccuped, the single p generally is preferred (c.f. cupping, supped). Both options are valid.

So, it was just a commentary mishap. That's good.

Re: Please Help me with this puzzle.

Hi;

Looking it says collectively they can only patronize 3 stalls, your solution is then invalid because you have them patronizing 4 stalls, 5,4,3, and 2.


In mathematics, you don't understand things. You just get used to them.

I agree with you regarding the satisfaction and importance of actually computing some numbers. I can't tell you how often I see time and money wasted because someone didn't bother to run the numbers.

I did not know that but I recommend working on the problem.

Re: Please Help me with this puzzle.

There are no solutions as the problem is worded. The book solutions is also wrong.

Yes, that's how I see it too.

What do you think of my wording change suggestion in my last post?

Gotta vanish for a bit...

Re: Please Help me with this puzzle.

That is correct, the wording given in the book means 2 stalls.

Re: Please Help me with this puzzle.

It would be nice if the OP could note his first post to make people aware of the flaw and the fix before they embarked on trying to solve the puzzle.

That is the way it is worded in the book.

Re: Please Help me with this puzzle.

Here, I am forced to disagree with my cousin phrontister. It is often good practice to work on problems that have no solution. One of my biggest complaints about my so called education was how my instructors slyly convinced me that

1) All problems have a solution. After all the textbooks are loaded with them. They never showed me one that did not.

2) All problems have nice neat answers like 1,2,3,π, √ 2, √ 3, 1 / 2, 1 / 3 or linear combinations of them.

In the real world not only does not every problem have a solution, lots of times you do not even no whether it does or it does not.

But I will make the change as a warning.

Re: Please Help me with this puzzle.

Counterarguments (even though I wholeheartedly dislike the education system):

1) That is usually only for high school level. At university, we are given several open-ended or unanswerable problems (usually just to show our effort or to discuss it)
2) Once again, that is usually only for high school level. At university, while most of the problems are proofs and the like, the computation problems are usually not in such a simple form.
