I messed up the problem...sorry. here it is again.

3 friends go to a restaurant to eat. When they are done, they get a bill for 25 dollars. They each give the waiter 10 dollars for a total of 30 dollars.

Since the waiter knows that these friends like to argue, he decides to give each person an equal amount of the change. So he gives each person 1 dollar and he keeps 2.

So, if each friend got 1 dollar back, then they spent 9 dollars each.

Therefore 9 x 3 = 27.

And the waiter kept 2 dollars.

Therefore 27 + 2 = 29.

29 dollars???? Where did 1 dollar go?

Bill is $25
Waiter keeps $2
Each person gets back $1 ($1 X 3 persons = $3)
$25 + $2 + $3 = $30.

The $2 the waiter kept is part of the $9 they each spent. The other $3 are the dollars each received back from the waiter.

Look from this prospective

each person bill was $ 8.3333337

3 x 8.3333337 = $ 25

since each gave $ 10 each for a total to $ 30

There was a $ 5 return

Divide 5 by 3

5 / 3 = $ 1.6666667

Each person would recieve $ 1.67 rounded to two decimal places.

The bill was 25 dollars

Each person gave $ 10

There was a $ 5.00 return

The waiter gave each person 1 dollar

The waiter kept 2 dollars

25 + 3 = 28

28 + 2 = 30

Everything is in order

Yes the 3 friends paid 27 dollars, 25 went to the restaurant and 2 went to the waiter.

You sum 27+2 when actually you should subtract 2 from 27.

It's only $25 not$30. 27 paid by the friends - 2 kept by the waiter = 25 in the cash register

so the friends spent $30 and each got $1 bac (total of $3)
$30 - $25= $5 (they should have gotten back $5) but they only got bac $3 ($5 - $3= $2) and the remaining $2 the waiter kept for himself! i hope this helps!!

So the bill is $25, and everyone gets a dollar back. so the amout paid for the bill is 25+2 for the tip.... every one gets a dollar back so 27 + 3 + 30

2007-01-15 03:20:04 · answer #7 · answered by Anonymous · 0 0

each paid $10
so, $10 x 3=$30
$30-$25 = $5----->balance of change
if each person gets $1 back and the waiter keeps $2, there will be no balance left..

faulty accounting

cost to each =25/3 =8.33
tip 2/3 = .67
change 1.0

total $30.00
