Mathematical Questions There is a tour group of 50 people, and they stay in a hotel.

3 single rooms. Then the number of people is 47, distributed between 2 and 3 people. Among them, the 3-person room has the lowest price.

You can have 3*(triple room)+28(two-person room)+3=50

The triple room has the lowest price, so it should satisfy the maximum number of people in the triple room 47/3=15 Yu 2

It can be calculated that if 2 people live in a two-person room, 45 people will be needed to occupy 15 triple rooms, plus three single rooms.

The minimum total price is 3×52×345×20=156900=1110 yuan.
