The population of Virginia is 7,980,000 people.

Let the population of Virginia be V.

Let the population of Georgia be G.

<u>Given the following data:</u>

Population of Georgia = 10.5 million

To find the population of Virginia:

Translating the word problem into an algebraic expression, we have;

24% percent less:

$\frac{24}{100}$ × $10500000$

$24$ × $105000$

24% of G = 2,520,000

Now, we can find the population of Virginia:

$V = G - 2,520,000$

$V = 10,500,000 - 2,520,000$

<em>V = 7,980,000 people.</em>

Therefore, the population of Virginia is 7,980,000 people.
