Answer:
The population size would be of 8,450 mice.
Explanation:
While the initial population of mice was 5,000 and there were 2,500 new births, the birth rate is 50% (2,500 / 5,000 = 0.5). Now, the 1,000 deaths, in turn, represent a mortality rate of 20% (1,000 / 5,000 = 0.2). In this way, at the end of the year, the number of mice became 6,500 (5,000 - 1,000 + 2,500).
Maintaining the same population growth rates, the number of new births would be 3,250 (6,500 x 0.5), and the number of deaths would be 1,300 (6,500 x 0.2), with which at the end of the second year the number of mice would be 8,450 (6,500 - 1,300 + 3,250).
