Answer: The equation to represent the total numbers of chairs in all of the meeting rooms at the hotel is given by :-

If m =7, then the total numbers of chairs in all of the meeting rooms at the hotel =2275.
Explanation:
Given: The total number of chairs in one meeting room = 325
Let the number of meeting rooms is represented by m.
Then the equation to represent the total numbers of chairs (y) in all of the meeting rooms at the hotel is given by :-

If m =7, then the total numbers of chairs in all of the meeting rooms at the hotel is given by :-

Hence, the total numbers of chairs in all of the meeting rooms at the hotel is 2275.
