    Answer: Approximately 8.78 million

    Step-by-step explanation:

    Since the population is growing at a rate of 3.1% each year, that is synonymous to percentage increase

    %increase = increase/initial population * 100

    Or

    (3.1 + 100) / 100 * initial population = 9.05 million

    = 1.031 * initial population = 9.05 million

    Initial population = 9.05million/1.031

    Initial population = 8.78 million
