The population of a species in the wild in Asia has been decreasing exponentially since 1980. This function represents the population of the species t years after 1980: W(t) = 20,000(0.95t).

The Wildlife Refuge Foundation noticed this trend before 1980 and decided to try to help reduce the population decline by breeding the species in captivity. The graph shows the number of these animals that have been born in captivity since 1980.

a. About how long will it take for the number of the species born in captivity to be equal to the number of the species remaining in the wild?
