A city has a population of 210,000 people. Suppose that each year the population grows by 4.75%. What will the population be after 9 years?



Answer :

Answer:

318864 people

Step-by-step explanation:

In order to solve for the population after a set time given a rate of growth, we can apply the equation [tex]A=P(1+r)^{t}[/tex], where A is the final amount, P is the starting amount, r is the rate as a decimal, and t is the time.

As a decimal, 4.75% is equal to 0.0475, so the equation will be [tex]A = 210000(1+0.0475)^9=318864[/tex] (always rounded down, as we cannot have a portion of a person)
