If 3 people go to lunch and the bill was $30 and they all give $10 and the waitress comes back with the waitress comes back and said the bill is 25 and gave them so each gave her $2 for the tip so if each got $1.00 back that means you each paid $9×3=27 plus the $2 .00 tip where did the other $1.00 go

Answer

No missing money

Step-by-step explanation:

Original money given to the waiter = $30

Each person paid $10

The waitress comes back with the waitress comes back and said the bill is $25

They gave her $2 for the tip

if each got $1.00 back

Balance = $1.00 × 3

= $3.00

That means each paid $9×3 = $27 including $2 .00 tip(recall that cost of the meal is now $25 plus $2 tip)

Each of them got $1.00 back

Total money spent = (cost of meal + tip) + balance of $3.00 given to them

= $27 + $3

= $30

Therefore, there is no missing $1.00

stops on an even number.
