Several packs of wolves were released into Yellowstone National Park in 1995. Ecologists need
to know how many wolves currently roam the national park to help determine the health of the
ecosystem in that area. They begin in March, capturing 30 wolves and marking them with a

scientists have captured 450 wolves, of which 25 had a tracking collar. How many wolves are in
Yellowstone national park?
