1. Common rats (Rattus norvegicus) in tropical areas breed continuously throughout the whole year. The instantaneous annual rate of increase for this species can reach 6.02 (this is a very large value!).

2. Refer to the problem (1) and recalculate the population size after two years now that you found that the carrying capacity for that population is of 25,000,000 individuals.
