Answer:
There were 200 children and 400 adults in the auditorium.
Step-by-step explanation:
Given that there were a total of 600 peoples in the event.
Let there were n children in the event.
So, the number of an adult in the event = 600-n
As the admission price for one child = 15 pesos
and the admission price for one adult = 25 pesos.
So, total admission price = 15n+25(600-n)
As total money raised = 13000 pesos
So, 15n+25(600-n)=13000
15n+15000-25n=13000
10n=15000-13000=2000
n=2000/10=200
Therefore, number of children = 200
and the number of adults = 600-200=400.
Hence, there were 200 children and 400 adults in the auditorium.
