Math Experts, please tell me I am RIGHT!

OK, here is the equation:

3 men go to a bar and order 3 drinks. The drinks total $25.

The bartender takes 3 of the dollar bills and gives them back to each of the customers, taking $2 as his tip.

OK, the men paid 10 each and received back 1 dollar, which means they each paid $9.00. 9 x 3 = $27. 27 + $2 tip = $29.

What happened to that extra dollar?

This is what I think the answer is. I say the answer is that the dollar is in the drinks! In otherwords, that missing dollar is in the original price of the drinks. You cannot evenly divide the $25 three ways. Well you could but It would equal $8.33 1/3 per drink. You can however divide it into 3 parts this way - $8 + $8 +$9. = $25.00

So when each of them paid 10, got a dollar back making each drink price $9.00, one had already paid $9.00 to begin with.

Does this sound right to you? This person who told me this problem said I would never figure it out. Initially I couldn't get the answer and I told him that I would figure it out in my dreams and later that night at 2:50 am I woke up saying Drinks, it's in the drinks. eek I dont' remember dreaming about that math problem but I did wake up saying that. lol

Someone please tell me I'm right lol This guy says he'll be my bitch if I get the answer pray

Each paid $10, meaning they paid in total $30.
30-25=5. that 5 was divided 3 to the men and 2 to the bartender (who might also be a man).

Right. That is the most obvious answer, notspats lol However if you take the fact that each men was returned $1.00, that means they each paid $9.00 each. 9x3 = 27, 27 plus the 2 tip is 29. The original total is $30. Where is that dollar?

The 3 ended up paying $27 total, including the $2 which went as a tip. The $2 should be subtracted, not added from the $27. The remaining $3 was split evenly among the 3 men.

Look at it the other way:

Cost of drinks = $25
Plus tip - $2

Total cost of drinks = $27

Cost of drinks divided by 3 men = $27/3 = $9.

Each man paid $10, got $1 back. So each man is in for $9.

It balances.

nod Absolutely correct!

It makes no sense to add $2 to the $27 since the $27 already includes the $2 tip... The initial $30... separated into 3 parts... the $2 tip... the $25 payment... and the $3 that the men keep... 2 + 25 + 3 = 30.

A good habit to get into, especially with math, is that if something isn't equaling out the way it should, try the equation another way, and another if that doesn't work either.

I don't think so. They each paid 10, the bill was $25 + $2 tip and so they each got a dollar back in change.

You know what? Please don't even tell me I did not get the answer correct mad I am so impressed that I even came up with an answer at all! lol Basically I was saying there is no missing dollar. If you are going to come up with a $29 figure, the dollar you are looking for is accounted for in the original price of the drinks!

Well in Israel, some restaurants added $1 to the bill since now they're required to hire a security guard. Maybe that's where it went smile

you got the math wrong...the way it's worded messes you up.

it's 25 (for the drinks) + 3 (left over) + 2 (tip) = 30

The drinks were not 9 a piece, they were 25 + 2 = 27.

But they didn't pay 9 per drink. The logic is messed up because it counts in multiplication and division to an addition and subtraction problem.

You can take it as paying 9 per drink, if you remember that tip is included...

Each paid 8.33333.... + 0.66666 (tip) = 9.

But adding the $2 to the $27 doesn't make sense.

yes, his mistake is coming up with a $29 total, which doesn't ever factor into this. It's $27 total, including the tip.

Moonbeam has it right. There is no missing dollar -- there just appears to be one because of the $27 + $2 calculation, which is improper for solving the problem at hand. It's a misdirection.

I don't think so. Maybe Moonbeam will disagree -- I'm not a math expert -- but it seems to me that the "missing dollar" can't be attributed to the drinks or anything else. If the missing dollar is "in" anything, it's the $27 + $2 step (which doesn't reflect reality) in the incorrect solution.

But knowing that one person already paid an extra dollar that the other 2 did not explains that if you wanna call a dollar missing that there really isn't one becuase it's already in the price of the drinks!
