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)
