Answer:
Violet reserved 7 small room and 14 large rooms in the hotel.
Step-by-step explanation:
Let, the number of small rooms reserved is x and that of the large room reserved is y.
Given that Violet reserved twice as many large rooms as small rooms, which altogether can accommodate 91 guests.
So, y = 2x .......... (1)
Again given that small rooms that can hold 3 people, and large rooms that can hold 5 people.
So, 3x + 5y = 91 ......... (2)
Now, substituting value of y from equation (1) to equation (2) we get,
3x + 5(2x) = 91
⇒ 13x = 91
⇒ x = 7
So, from equation (1) we get, y = 2x = 14
Therefore, Violet reserved 7 small room and 14 large rooms in the hotel. (Answer)
