Answer:
C 20,000
Explanation:
Step 1 find difference in population of 2000 to 2005
2,900,000 - 2,800,000 = 100,000
So from 2000 to 2005 the population has risen a total of 100000 people
Step 2 find rate of change PER YEAR
from 2000 to 2005 is 5 years.
the population rose 100,000 during those 5 years
rate of change = population increase over time
Thus, average rate of change = 100,000 / 5 = 20,000
Which means that about every 1 year the population increases by 20000
