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
