Answer:

children = 177, adults =215

Step-by-step explanation:

im too lazy to write but solve this with a systeme

x(children),y(adults)

x+y=392

x=392-y

2.5y+1.25x=758.75

2.5y+1.25(392-y)=758.75

2.5y+490-1.25y=758.75

490+1.25y=758.75

1.25y=758.75-490

1.25y=268.75

y=268.75/1.25

y=215

x=392-215=177(number of kids)
