Answer:
x + y = 47 (eqn 1)
x + 2y = 79 (eqn 2)
Solving the simultaneous equation,
The hotel has 15 single rooms and 32 double rooms.
Step-by-step explanation:
English Translation
The management of Colegio Montes and the parents are organizing a cultural trip to Guanajuato for second grade students and their teachers. Students will sleep in double rooms and teachers in singles. The hotel has double rooms (2 beds) and single rooms (1 bed), totaling 47 rooms and 79 beds. To confirm if they can be accommodated, they want to know how many rooms there are of each type. If "x" denotes single rooms and "y" denotes double rooms, Write the system of equations that represents the situation: Equation that represents the number of rooms (1) Equation that represents the number of beds (2)
Solution
The number of single rooms = x
The number of double rooms = y
The number of beds in single rooms = x
The number of beds in double rooms = 2y
Total number of rooms = 47
Total number of beds = 79
Sum of single and double rooms = Total number of rooms
x + y = 47 (eqn 1)
Sum of the beds in the single rooms and the beds in the double rooms = Total number of beds
x + 2y = 79 (eqn 2)
Writing the equations together
x + y = 47 (eqn 1)
x + 2y = 79 (eqn 2)
Solving the equations simultaneously,
x = 15, y = 32
Hence, the hotel has 15 single rooms and 32 double rooms.
Hope this Helps!!!
