Interpret and evaluate situations involving percentage changes using the GeoGebra applet.[br][br]To begin, click the BUTTON to generate a set of problems. Solve the problem displayed on the screen and type your answer into the INPUT BOX. A checkmark will confirm if your answer is correct. Once you've completed the current problem, click the New Problem button to move on to the next question. Repeat this process for each new problem set.
Reflecting on the percentage change problems you solved using the GeoGebra applet, how can percentage increase and decrease be applied to real-world situations, such as financial savings, price discounts, or population growth? Provide a specific example of a real-life situation where calculating percentage change would be important, and explain how you would approach solving it based on what you learned during the task.
