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.
