To find the percent change in the number of members in the chess club, you can use the following formula:
Percent Change = [(New Value - Old Value) / Old Value] * 100
Let's calculate the percent change step by step:
1. Old Value: The number of members in the chess club last year was 20.
2. New Value: The number of members in the chess club this year is 15.
Now, let's substitute these values into the formula:
Percent Change = [(15 - 20) / 20] * 100
Simplifying further:
Percent Change = [-5 / 20] * 100
Percent Change = -0.25 * 100
Percent Change = -25%
Therefore, the percent change in the number of members in the chess club is -25%, which indicates a decrease of 25%.
