Question

it was predicted that a country will have an elderly population (65 and older) of 8,980,000 in the year 2050 and that this will be 22.9% of the population. what is the total predicted population of this country in 2050?

Answer 1

To determine the total predicted population of the country in 2050, we used the given percentage of the elderly population (22.9%) and the number of elderly individuals (8,980,000), which resulted in a total population of approximately 39,216,593.

Step-by-step explanation:

To find the total predicted population of the country in 2050, we can set up a proportion because we know that the elderly population makes up 22.9% of the total population. Let's denote the total population as T. The elderly population is already given as 8,980,000.

The proportion can be set up as follows:
Elderly Population / Total Population = Percentage of Elderly Population / 100

Plugging in the known values:
8,980,000 / T = 22.9 / 100

To find T, we solve for it by multiplying both sides of the equation by T and then dividing both sides by 22.9, which gives us:
T = 8,980,000 / (22.9 / 100)

Calculating this, we find:
T = 8,980,000 / 0.229
T = 39,216,593 approximately

Therefore, the total predicted population of the country in 2050 is approximately 39,216,593.

Answer 2

The total population of that country by the year 2050 is predicted to be 39,213,973.

Step-by-Step Explanation:

Let the total population of a country predicted in 2050 = x

Elderly population of a country by the year 2050 = e = 22.9%

Elderly population in the year 2050 is predicted to be 8,980,000 and it is 22.9 % of the total as explained in the question.

Calculating the Total population 'x' in 2050:

We can calculate the total population 'x' using the following equation

22.9 % of x = 8980000

(22.9/100)*x = 8980000

`22.9 % of x = 8980000(22.9/100)*x = 8980000`

⇒
`x = 8980000*100/22.9\\x = 898000000/22.9\\<strong>x = 39213973</strong>`
