    Answer: the population of the world in 2030 is 8693273454

    Step-by-step explanation:

    We would apply the formula for exponential growth which is expressed as

    y = b (1 + r) ^t

    Where

    y represents the population, t years after 2018.

    t represents the number of years.

    b represents the initial population.

    r represents rate of growth.

    From the information given,

    b = 7,632,819,325

    r = 1.09% = 1.09/100 = 0.0109

    Therefore, the equation that can be used to predict the population of the world after 2018 is

    y = 7632819325 (1 + 0.0109) ^t

    y = 7632819325 (1.0109) ^t

    In 2030, t = 2030 - 2018 = 12 years

    y = 7632819325 (1.0109) ^12

    y = 8693273454
