Sagot :

Five years ago, the number of students that were involved in extracurricular activities was 500.

This year, the number of students that were involved in extracurricular activities is 340.

To determine the percentage decrease of the students that were involved in extracurricular activities you have to calculate the difference between the starting value and the final value, that is, the difference between the number of students that were involved in extracurricular activities 5 years ago and the number of students that are involved in extracurricular activities this year:

[tex]StartingValue-FinalValue=500-340=160[/tex]

Then, divide the result by the starting value and multiply the result by 100:

[tex]\frac{160}{500}*100=\frac{8}{25}*100=32\%[/tex]

The number of students that are involved in extracurricular activities decreased by 32%.
