Answer 1

Answer:

36,995,475

Step-by-step explanation:

In the year 2050, a country's elderly population is predicted to be 8,176,000

This is 22.1% of the tota population

If x=total population in the year 2050

and 22.1% of x = 8,176,000

Then:

22.1% of x = 8,176,000

$\frac{22.1}{100}x= 8176000$

On Cross multiplication

22,1x = 817,600,000

x=$\frac{817600000}{22.1}$ =36995475.11

We jettison fractional values because we are dealing with population.

Therefore, In the year 2050, the total population of the country will be 36,995,475
