In 1859 Thomas Austin wrote to his brother and asked for twenty-four (24) rabbits. Additionally, due to direct competition for food and habitat, the population of many native animals, such as the greater bilby and the pig-footed bandicoot, has declined dramatically. By the 1900s, the rabbits had reached the Northern and Western territory. a) Determine P (t), the function that gives the population at time t, and the differential equation describing the population growth.

In 1859, a man named Thomas Austin imported 24 wild rabbits from England and released them into the wild for hunting purposes on his property, Barwon Park, near Winchelsea, Victoria.
