cuz u don't calculate it that way. what you had to pay was $25 + $2 and not $30 -$2. what they paid was exactly correct. 3 x (10-1) = 27 = 25 + 2.作者: Hyde 時間: 2008-9-26 08:47
each person paid $9, $25 goes to the meal and $2 as tips = $27
each person pull out a dollar = $3
$3 + $27 = $30作者: mui122 時間: 2008-9-26 12:28

Here's your problem
Your question was faulty to begin with
why would you subtract the tips instead of the money returned to the payers作者: Catpiano 時間: 2008-9-26 22:06
兩 鎊 是 小 費 , 很 合 理 ??
If you are going to pay just 8 % tips .... I dont think you can leave the resturant la.. lol ..
I remember it was the question from my P3 school ...
So .. 2x yr ago .. 8% tips was still reasonable ...
If it happens today .. $25 bill, pay $28-30 is more reasonable la... 作者: pepsis2 時間: 2008-9-27 13:56
