The number of people in the world who natively speak Language A is 330 million. The number of people in the world who natively speak Language B is 260 million. Language experts who chart the growth of both languages claim that in five years, the number of persons who natively speak Language A will be approximately 450 million, and the number of persons who natively speak Language B will be approximately 300 million. In the table below, identify the average annual rate of growth of Language A native speakers, and then identify the difference between Language A’s and Language B’s average annual growth rates. Make only two selections, one in each column.

1. The average rate of growth for a certain language is equal to the difference of native speakers now and then, divided by the number of years. 2. Let's calculate the average rate of growth for languages A and B: - Language A: \frac{# \ of \ native \ speakers \ now - # \ of \ native \ speakers \ then}{# \ of \ years} = \frac{450 \ million - 330 \ million}{5} = 24 million per year. - Language B: \frac{# \ of \ native \ speakers \ now - # \ of \ native \ speakers \ then}{# \ of \ years} = \frac{300 \ million - 260 \ million}{5} = 8 million per year. 3. The difference between the two will be 24 million - 8 million = 16 million per year. 4. Our answer is: 24,000,000 and 16,000,000 .
