Dr. Ricci owns a hotel with 200 guestrooms. On Monday evening, Dr. Ricci's property had 150 out of its 200 rooms occupied. The General Manager (GM) calls Dr. Ricci on Tuesday morning and reports to him that the hotel's occupancy for Monday night was?

The ocupancy for that night was 75%.

Step-by-step explanation:

In order to solve this problem we need to calculate the occupancy of the hotel in percentages, this is done by using a rule of three in such a way that the total capacity of the hotel is 100% and the number of rooms being used in that certain night is the percentage we want to find. So we have:

200 rooms -> 100 %

150 rooms -> x %

200/150 = 100/x

200*x = 150*100

200*x = 15000

x = 15000/200 = 75 %

The ocupancy for that night was 75%.

water molecules will move from the side of higher water concentration to the side of lower concentration until both solutions are isotonic. at this point, equilibrium is reached. in an isotonic solution, the flow of water in and out of the cell is happening at the same rate.

hope this < 3
