Calculation of the Ticket Price Change

To determine whether the ticket price increased or decreased as a result of the owner's actions, let's break down the information provided:

1. The owner of the nightclub increased the ticket prices by 25%. 2. As a result, the number of visitors decreased. 3. In response to the decrease in visitors, the owner reduced the ticket prices by 20%.

To calculate the overall change in the ticket price, we need to consider the two actions taken by the owner: the initial increase of 25% and the subsequent decrease of 20%.

Let's assume the original ticket price was $100.

Calculation Steps:

1. Increase of 25%: The ticket price is increased by 25% of $100, which is $25. Therefore, the new ticket price after the increase is $100 + $25 = $125.

2. Decrease of 20%: The ticket price is decreased by 20% of $125, which is $25. Therefore, the new ticket price after the decrease is $125 - $25 = $100.

Conclusion:

After the owner initially increased the ticket prices by 25% and then decreased them by 20%, the final ticket price returned to the original price of $100. Therefore, the overall change in the ticket price was no change.

Please note that the calculations provided are based on the assumption that the original ticket price was $100. The actual values may vary depending on the specific circumstances of the nightclub and the ticket prices involved.
