Answer 1

To calculate the rate of change (decrease or increase), use the formula [(final value - initial value)/initial value] *100.

The number of students in a chess club has fallen from 18 to 12. What is the

percentage decrease? Round off to the nearest percentage.

[(12-18)/18]*100=33.33333=33.3%

Officer Brimberry issued 16 tickets for traffic violations last week, but only 10 this week. What is the percentage decrease?

[(10-16)/16]*100=37.5%
