This discussion board is a place to discuss our Daily Challenges and the math and science
related to those challenges. Explanations are more than just a solution — they should
explain the steps and thinking strategies that you used to obtain the solution. Comments
should further the discussion of math and science.

When posting on Brilliant:

Use the emojis to react to an explanation, whether you're congratulating a job well done , or just really confused .

Ask specific questions about the challenge or the steps in somebody's explanation. Well-posed questions can add a lot to the discussion, but posting "I don't understand!" doesn't help anyone.

Try to contribute something new to the discussion, whether it is an extension, generalization or other idea related to the challenge.

Stay on topic — we're all here to learn more about math and science, not to hear about your favorite get-rich-quick scheme or current world events.

This is funny, and yet so true. This is kind of like how it works between hospitals and insurance companies, while you pay the 20% "co-pay" which really works out to nearly 100% of the actual cost. The rest is just money shuffled between hospitals and insurance companies, i.e. hospitals overcharge, and so do the insurance companies on coverage hospitals have to have.

Maybe a better example would be Corporation ABC owning 90% of the stocks of Corporation XYZ, which in turn owns 90% of the stocks in Corporation ABC. Each corporation claims to be worth $1 Billion, because all that stock buying and claims to be worth that much has driven up stock prices. How much of each are actually worth? Let's say each are start-up internet companies with little or no real physical assets.

Heh right?? And the thing is, unless you're a mathematician, you'll never figure it out! I had to resort to classifying the transactions like I did with the 1$ problem in order to figure this out; otherwise, you'll never know! And the one who sells the box always wins! This is how corporations do it, really. Like in CVS, if they give out 20% coupons, they'll make everything "ON SALE" ahead of time (since sale items cannot be couponed) so that you actually pay more, but it looks like you'd pay less.

THIS, right here, is why math education kicks in. You can save lots more money if you know how much you're paying for your goods and services.

I recall reading an artricle somwhere that the average American knows very little about finance and investments, and Wall Street guys want to keep it that way.

Oh, that one's an oldie, but the problem I had in mind is a variation of it. But, yes, that one is the best analogy to the comic strip Muradeli has put up here.

The person who buys the box loses $10, because in addition to the $30 he uses to buy the box, there is also the $20 that he put into the box.

aw don't spoil the fun

This does remind me of a math problem involving drunks at a restaurant, maybe I should post it sometime

No harm to fun intended :)

@Michael Mendrin Are you talking about the "Where's the Missing $1" problem? A believe I've seen it on B'ant also.

The new owner of the box (the one who is not on Brilliant.org) takes out $50 from his wallet, gets $40 and still stays happy.

This is a severe case of satisfaction...:D lol.
