Question

A theater predicts selling 400-8p tickets when each ticket is sold at p dollars.If the ticket price is 5 dollars, what is the number of tickets sold and the revenue the theater should make?

Answer 1

To find the prediction for the number of tickets sold at 5 dollars, we need to use the given expression and replace "p" by 5. This is done below:

`\begin{gathered} \text{tickets sold = 400-8}\cdot p \\ \text{tickets sold =}400-8\cdot5=360 \end{gathered}`

The revenue can be found by multiplying the number of tickets sold by 5.

`\text{revenue = 360}\cdot5=1800`
