Individuals from this captive breeding population have been used to reestablish a wild condor population. The wild population currently has 50 individuals. The species will no longer be considered endangered when the newly established population has 375 individuals. If the wild condor population expands exponentially, and it has a birth rate of 0.07 and a death rate of 0.02, how long will it take before the species is no longer considered endangered?
