This The New Inn has 40 rooms and a restaurant. How many people are needed and how to allocate the specific personnel?

Two room attendants, 8: 00 a.m. to 8: 00 p.m., take a break and pay by the piece. There are two people at the reception desk, from 8 am to 8 pm, during the break, pay by the piece. I booked a 40-room hotel at night, and I need to control all the costs. Otherwise, the profit margin is small. The business situation of the restaurant is determined by the situation of the guests in the room. I need three people, a cook, a coolie and an aunt to help me choose vegetables and wash dishes. A security guard will be assigned from 8: 00 to 8: 00 in the evening to be responsible for the safe and timely services required by the guests, such as opening the door and delivering consumables. There are eight people in all.
