Answer:

In 18 years time, the population of the city is approximately 705,084

Step-by-step explanation:

From the given information, the initial population is

[tex]P_0=200000[/tex]

The growth rate is 7% or r=0.07.

For a population with a continuous growth rate, the equation is that models it is:

[tex]P(t)=P_0 {(e)}^{rt} [/tex]

[tex]P(t)=200000 {(e)}^{0.07t} [/tex]

To find the find the population after 18 years, we substitute t=18 into:

[tex]P(18) = 200000{(e)}^{18\times 0.07} [/tex]

[tex]P(18)=705084.3[/tex]
