Suppose a study is completed that finds that the number of cockroaches in Chandler decreases by 18% every 12 years. In 2020, there were approximately 3.5 million cockroaches in Chandler. 1. Assuming the number of cockroaches is changing exponentially, how many cockroaches do you estimate there will be in 2025 (5 years later)? 2. Demonstrate mathematically why it is not true that the number of cockroaches in Chandler decreases by 9% every 6 years. 3. Determine how long it will take for the number of cockroaches in Chandler to decrease by 50%.
