Practice with Exponential Growth and Decay Applications 1. The mice population is 25,000 and is decreasing by 20% each year. Write a model for this situation. 2. Given the model for #1, what will be the mice population after 3 years? The number of mosquitoes at the beach has tripled every year since 1999. In 1999, there were 2,500 mosquitoes. Write a model for this situation. 3. 4. Given the model for #3, how many mosquitoes will there be in 2005? 5. Given the exponential modelf (x) = 200(.80)*, tell whether the model represents exponential growth or decay, name the growth/decay factor, and name the growth/decay percent. 6. I bought a car for $25,000 but its value is depreciating at a rate of 10% per year. How much will my car be worth after 8 years? 7. You deposit $1,500 in an account that pays 5% interest compounded annually. Find the balance after 6 years. 8. How much more money would I earn if the interest in #7 is compounded monthly instead of annually? 263
