The first thing we need to do is identify the important values, our variables, and our equations that model or describe our problem.

• A total of 560 tickets were sold.

• Tickets can be ,A,dult or ,S,tudent


A+S=560\to(1)

• The total of tickets sold $3166

,

• The value of the Adult ticket is $8

,

• The value of the Student ticket is $3.5


8A+3.5S=3166\to(2)

We can see that A and S correspond to the number of Adult or Student tickets sold. We solve the equations to find our numbers.


A=560-S\to\text{(1)}
\begin{gathered} 8(560-S)+3.5S=3166 \\ 8*560-8S+3.5S=3166 \\ S(3.5-8)=3166-4480 \\ -4.5S=-1314 \\ S=(-1314)/(-4.5) \\ S=292 \end{gathered}
\begin{gathered} A=560-292 \\ A=268 \end{gathered}

In total, 292 Student tickets and 268 Adult tickets were sold.
