**How many of each type of ticket were sold?**

\(\text{Let tickets for students $= x$ } \\ \text{Let tickets for adults $= y$ } \)

\(\begin{array}{|rcll|} \hline \mathbf{x+y} &=& \mathbf{203~tickets} \\ y &=& 203 - x \\\\ \mathbf{$4.50x + $9y} &=& \mathbf{$1485} \\ 4.50x + 9(203 - x) &=& 1485 \\ 4.50x + 1827 - 9x &=& 1485 \\ -4.50x + 1827 &=& 1485 \\ -4.50x &=& 1485-1827 \\ -4.50x &=& -342 \quad | \quad *(-1) \\ 4.50x &=& 342 \quad | \quad :4.50 \\ \mathbf{x} &=& \mathbf{76~tickets} \\\\ y &=& 203 - x \\ y &=& 203 - 76 \\ \mathbf{y} &=& \mathbf{127~tickets} \\ \hline \end{array}\)
