Answer:
16,000 people
Step-by-step explanation:
Let's write a ratio
8,000:20,000
Let's write another ratio
x:40,000
We can write a percent proportion.

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

Answer:
22/24
ALL TOGETHER there is 24 donuts. 
take half of 24, or 24 divided by 2, and you get 12. 
so we know 12 of the donuts are vanilla with sprinkles. 
then 2 had strawberry frosting and the rest had chocolate and sprinkles. 
we took 12 away so we only have twelve left and if 2 of those 12 are strawberry with no sprinkles and the rest are chocolate WITH sprinkles, this means 10 are chocolate with sprinkles.
so 10 chocolate and sprinkles +12 vanilla and sprinkles=22 donuts with sprinkles out of 24 donuts total
