Respuesta :

we have

adults = a = 40 + s

studentes = s

then:

[tex]\begin{gathered} a+s=440 \\ a=s+40 \end{gathered}[/tex]

solve:

[tex]\begin{gathered} s+40+s=440 \\ 2s+40=440 \\ 2s+40-40=440-40 \\ 2s=400 \\ \frac{2s}{2}=\frac{400}{2} \\ s=200 \end{gathered}[/tex]

then:

[tex]a=s+40=200+40=240[/tex]

answer:

adults = 240

students = 200
