Question

the table shows the number of tickets sold on opening and closing night for each event. the students want to know which event had the most improved attendance. how did the ticket sales for the chorus performance change? the sales for the chorus performance ? by ? tickets.

Explanation:

Step1: Calculate the change in ticket sales

To find the change in ticket sales for the Chorus Performance, we subtract the opening - night ticket sales from the closing - night ticket sales. The formula for the change is \(Change=Closing\ night\ sales - Opening\ night\ sales\).
For the Chorus Performance, the opening - night sales are \(40\) and the closing - night sales are \(60\). So, \(Change = 60−40\).

Step2: Simplify the expression

\(60−40 = 20\). Since \(60>40\), the sales increased.

Answer:

The sales for the chorus performance increased by \(20\) tickets.
