Scrooge invests $500. He found a bank that would pay him 4% Interest, compounded quarterly. If he deposits the whole $500 and does not deposit or withdraw any other amount, how much money would he have after 4 years? How long would it take him to double his money? 2. . Since January 1980. the population of Mondale has grown according to the mathematical model y = 720,500(1.022)" , where x is the number of years since urinary-1930. Explain what the numbers 720,500 and 1.022 represent in this model. What would the population be in 2000 ifthe growth continues at the same rate?. When would you predict the population of Mondale reach 1,000,000
