My reasoning was that the restruant owner has $25 left, each travler has $1 and the waitress $2 which adds up to $30

Turbro is correct because 25/3 is 8.33 which is what it should have cost, 1 is what each travller got back 8.33*3 + 1*3 = $28 now add the $2 the waitress kept and oyu get your $30

They were charged $25 after the refund and the waitress only gave them $3 back and pocketed $2. The only money "in play" due to the greedy thieving waitress was $28. I Just subtracted that right off the bat because it became irrelevent to the math problem.

Then I divided the money "in play" by 3 to determine what each person actually paid and subtracted $1 from that.

Oh...and my other post SHOULD read NOT including the $2 the waitress pocketed. I had a typo, so it sounds a bit funky. I just noticed it now...

God I can't believe it lol.

They each pay 10, they each get 1 back. That equals 9 each. Not 8.66, not 9.33, but 9 flat.

If you don't believe me, check it on your calculator. 10-1=9.

Three guys each ended up paying 27 when they actually only had to pay 25. So where did the surplus 2 go? It's in the waitresses pocket. 27-2=25

Quit saying they've each payed a fraction of a dollar - they haven't!! It's perfectly obvious that having given 10 and had 1 returned to them they've paid 9.

The answer doesn't lie in inventing weird fractions of dollars, the answer lies in recognizing that you subract 2 from 27 to get 25 (the amound left in the till), NOT add 2 to 27.

Correct.

People are making it more complicated for themselves than they have to. The solution has more to do with how you see the problem rather than any mathematical processes.
