Answer:
[tex]C=16n[/tex]
Step-by-step explanation:
This situation could be represented as a linear equation, since the cost of each ticket is the constant rate of change:
[tex]\begin{gathered} C=kn \\ \text{where, k is the constant and n is for tickets} \end{gathered}[/tex]
As a first step, we need to calculate the cost of each ticket:
[tex]\begin{gathered} k=\frac{80}{5} \\ k=\text{ \$16} \end{gathered}[/tex]
Hence, the equation that represents the cost, C for n tickets would be:
[tex]C=16n[/tex]
