Answer:
The growth rate is 1250 per year.
Explanation:
- First of all, lets consider the population number in both years;
The initial population is 1200, and
Final population is 3700.
- Total increased population is (3700- 1200) = 2500
So 2500 population were increased in (2006 - 2004)= 2 years.
- To find the annual growth rate: (Increased population/ time span in years)= 2500/2= 1250 per year.
- Hence 1250 population was added per year in walleye from 2004 to 2006.
