Question

In a certain population of rabbits one year, 25 new rabbits are born and 5 move into the population from surrounding areas. However, 10 rabbits die, and 5 leave the population. What is the population change?​

Answer 1

Answer:

Population change is 15

Explanation:

To calculate the change in populations, we add up the immigrants and births and the subtract the deaths and emigrant from it

Change in pop = (birth + immigrants) - (death + emigrants).

Where birth is 25, immigrants is 5, death is 10 and emigrants is 5.

Change in pop = (25+5) - (10+5)

= 30-15

Change in population is 15.
