Answer:
The difference is 60.
Explanation:
Since no more than 5 people can stay in each of the 15 rooms, we can multiply these numbers to get the largest amount of guests.
5 x 15 = 75
We assume the smallest amount can be 1 person in each of the 15 rooms.
1 x 15 = 15
We then subtract the smallest from the largest to find the difference.
75 - 15 = 60
