It was predicted that a country will have an elderly population (65 and older) of 8 comma 176 comma 000 in the year 2050 and that this will be 22.1% of the population. What is the total predicted population of this country in 2050?

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

On Cross multiplication

22,1x = 817,600,000

x= =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

for the points! : )

-13

step-by-step explanation:

f(x)=2x-5 for f(-4)

f(-4)   means let x=-4

f(-4) = 2(-4) -5

f(-4) =-8-5

      = -13
