Activity 10.2: Practice - Solving for Percent Change
YOUR TASK
Determine whether the change is a percentage decrease or percentage increase and solve for percent change.
This GeoGebra applet allows you to generate two random values by clicking the "New Values" button.
You can then enter your calculated percentage change into the provided input field. The applet will instantly check your answer and tell you if it’s correct, indicating whether it represents an increase or a decrease.
To further assist with understanding, you can click the CHECKBOX to view the solution using bar models. This visual representation helps illustrate the percentage change between the two values.
Question 1
If the applet shows a positive percentage for your percentage change, what does this mean about the new value compared to the original value?
Question 2
How would the percentage change differ if the initial and new values were swapped? How does this affect your calculation and interpretation?
