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 spring play change?
the sales for the spring play by tickets.

Explanation:

Step1: Calculate the change in ticket sales

To find the change in ticket sales for the Spring Play, we use the formula: \( \text{Change}=\text{Closing Night Sales}-\text{Opening Night Sales} \).
For the Spring Play, the opening - night ticket sales \( a = 200 \) and the closing - night ticket sales \( b=230 \).
So, the change \(=b - a\).

Step2: Substitute the values

Substitute \(a = 200\) and \(b = 230\) into the formula: \(230-200\).
\(230-200 = 30\).

Answer:

The sales for the spring play increased by \(30\) tickets.
