im stumped on crazy question. im sure its something hella obvious but i cant figure out the wordplay on this. Have a crack at it.

3 girls get a hotel room. It cost 30 dollers so they all throw 10 a piece.
Later that night the manager says to give them 5 dollers back. The bag boy
does not know how to split 5 evenly so he gives them all a dollar back and keeps 2. So if all 3 girls threw 9 that would be 3 * 9 which is 27 and then add the 2 its 29.. where did that extra dollar go?

you get 27 by subtracting 3 from 30. you also subtract the remaining 2 to get to 25. why would you add it?

the math is just wrong the way you're asking it.

to look at it another way... if they each spent 9 dollars instead of 10, they're saving 3 dollars. in the 9x3=27 part, you're multiplying the 9 dollars times 3 people, which equals 27 dollars total. when you add the 3 dollars they saved it equals 30, as it should. no reason to add two as it isn't part of the equation.

30 hotel total
-5 bagboy takes
--
25 new hotel total

5 split to bellboy 2 - girls 3

The bell boys gives the 2 bucks back to hotel...
giving hotel grand total 27 bucks

the girls have the extra 3... 27 + 3 = 30... there is no missing dollar





your confussd because

25 / 3 = 9.33333333

if you do it the way it reads, you basically round out a dollar... my best guess

lol second math mistake ive picked up in 2 threads. im guessing this one is a typo though but 25/9 is less than 9 not 9.33333. im guessing you meant to type 30 though so you still get a pass mark.

MY 5YR OLD FIGURED THAT OUT LIKE IN 2 SECONDS....YOU STUPID!....

That's the whole point. It sounds like a first to third grade math problem. I think dude switched it up a little bit in here though, but in reality... he was helping his kid with math homework LOL!

I get stuck on math sometimes with helping my son with homework and thought of either tweeting it or posting it in here too LMAO!!!!!!!!!
