There were 25 million people in 1980 (when t = 0) and 55 million people in 1990. Find an exponential model for the population (in millions of people) at any time t, in years after 1980. (Note: if you use decimal approximations for the numerical constants in your work, be sure to retain enough significant figures through your work to ensure that subsequent answers are correct.) What population do you predict for the year 2000? Predicted population in the year 2000 = What is the doubling time? Doubling time = Note: You can earn partial credit on this problem.
