Answer:
200 children.
180 adults.
Explanation:
let x=Children and y=Adults
create 2 equations.
x+y = 380
2.50x+5.80y = 1544
solve for x in the first equation and plug into the second equation.
x = 380-y
2.50(380-y) +5.80y = 1544
distribute and simplify.
950 + 3.3y = 1544
simplify
3.3y = 594
y = 180
plug y back into first equation and you get that there were 200 children.
