Answer:
C. 120,000 people
Step-by-step explanation:
First thing I did was divide 90 by 45 which gave me 2 as my answer. So now I know that the population 90 years from now will be doubled twice (x4). So I did...
[tex]30,000 \times 4 = 120,000[/tex]
Answer:
80,000 people
Step-by-step explanation:
First, find out how many times the population will double. Divide the number of years by how long it takes for the population to double.
68÷34=2
The population will double 2 times.
Now figure out what the population will be after it doubles 2 times. Multiply the population by 2 a total of 2 times.
20,00022=80,000
That calculation could also be written with exponents:
20,00022=80,000
After 68 years, the population will be 80,000 people.
