Quizplus · Accepted Answer

To calculate the average annual growth rate in millions, we need to find the difference between the population of 2000 and 1990, which is 6.1 billion - 5.3 billion = 0.8 billion. Then we divide this number by the number of years between 1990 and 2000, which is 10. Finally, we convert billion to million by multiplying 0.8 by 1000, which gives us 800 million. To find the average annual growth rate in millions, we divide 800 by 10, which gives us 80 million, or 82 million rounded to the nearest million. Therefore, the answer is B.
