2002

Step-by-step explanation:

Given :

To Find : Determine the year in which the country had or will have a population of 189,698,000.

Solution:

We are given an equation which represents The population of a certain country.

where P is the population in millions.

x is the number of years since 1980

Now we are supposed to find the year in which the country had or will have a population of 189,698,000.

P   represents population in millions. Then,  P = 189.698

Substitute P in equation :

So, x≈ 22

Since x is the number of years since 1980

So, the year in which the country had or will have a population of   189,698,000. = 1980+22 = 2002

Hence  the country had or will have a population of 189,698,000 in 2002.
