Your baseball team is holding a silent auction as a fundraiser dinner to pay for the team uniforms. The list shows all the expen
ra1l [238]

The first step to determine the function is to find the total cost of the auction. This is done by adding all the prizes and the cost of the food.

\begin{gathered} \text{ cost}=320+150+30+400 \\ \text{ cost}=900 \end{gathered}

The total cost of the auction is $900. Since the cost of 50 tickets should be able to cover the cost, we need to divide the total cost by the number of tickets to determine the cost of each ticket.

\begin{gathered} x=\frac{900}{50} \\ x=18 \end{gathered}

Each ticket must be sold as $18. The whole function is:

f(x)=18\cdot x-900
