How much is it reasonable for the hotel to report the loss of linen in a month?

For example, there are 320 rooms in a hotel, including 3 sets of linen, 280 times of quilt cover washing, 230 times of pillowcase washing and 250 times of towel washing. The annual occupancy rate of rooms is predicted to be 70%, and the annual consumption quota of sheets in this hotel is calculated.

{1} Actual annual washing times of each quilt cover.

360 days ÷3 sets× 70% occupancy rate ≡84 times

{2} Actual washing years of quilt cover

The times of quilt washing is 280 times ÷84 times = 3.3 years.

{3} After the new quilt cover has been used for 3 years, the loss reporting rate is different every year. Here is an example of an annual loss report form for reference.

Underwriting loss rate

2% in the first year, 0/5% in the second year, 35% in the third year and 48% in the fourth year.

For example, the hotel has 600 beds of quilt cover.

After the first year, the loss reporting rate is 600× 2% = 12 beds.

After the second year, the loss reporting rate is 600× 15% = 90 beds.
