Archy [21]

Answer:

16,000 people

Step-by-step explanation:

Let's write a ratio

8,000:20,000

x:40,000

We can write a percent proportion.

\frac{8,000}{20,000} =\frac{x}{40,000}

We can see that the relationship between the denominators is multiplied by 2 so that means the relationship between 8,000 and x is x is 2 times greater than 8,000
