Question

In 1950, the population of Alaska was about 128,535. That was about 20.5% of the population of Alaska in the year 2000. About how many people lived in Alaska in the year 2000?

Answer 1

The population of Alaska in the year 2000 is 627,000.

Explanation:

Given,

Population of Alaska in 1950 = 128,535

Solution,

Let the population of Alaska in 2000 be 'x'.

Now according to question, the population in the year 1950 is 20.5% of the population in the year 2000.

The population in the year 1950 is equal to 20.5% multiplied with the population of the year 2000.

So we can frame it as;

`x*20.5\%=128,535`

To change the percentile we will divide by 100, and get;

`(20.5x)/(100)=128535\\\\20.5x=128535*100=12853500\\\\x=(12853500)/(20.5)=627,000`

Hence The population of Alaska in the year 2000 is 627,000.
