Yes, we pay total 3,000.- for the first time.
However, you must delete 200.- from your caculation, because the hotel staff alreay take it into his or her pocket.
So, actually we pay 3,000 - 200 = 2,800 for the hotel charge (933.33 per person)
Then, when we got the money back 300.- (100 per person)
It's mean that we pay only 933.33 - 100 = 833.33 per person for the hotel charge.
Now, you can apply the same concept for the other questions like this.
OK na krub. :)
