Do hotels charge more money for each person that stays in one room? -

I m young, and I ve never been in a hotel before, maybe once. But I need someone to fill me in on the expenses of staying in a hotel. Its for a math project. I mostly need how much a hotel like The New York Time would cost for 5 days for 6 people, and 3 rooms. (I would like the cost per day)

Most room rates are based on double occupancy. There is usually a charge for more than 2 people in each room.
