Final answer:
The hotel chain will save a total of 54,000 minutes per day by reducing the cleaning time by 2 minutes for each of their 27,000 rooms.
Step-by-step explanation:
Calculating the time saved per day by the hotel chain involves understanding basic arithmetic and multiplication.
If the hotel chain reduces the cleaning time by 2 minutes per room, and there are 27,000 rooms to clean, the total time saved can be calculated as follows: 2 minutes saved per room × 27,000 rooms = 54,000 minutes saved per day. Thus, the correct answer is: A) 54,000 minutes.
