The correct answer is - b. 0.0357 wolves/mi.
To get to the correct result about the density of the wolf population in the Yellowstone National Park, we only need to divide the number of the wolf population by the total area that the national park covers.
124 / 3472 = 0.0357
The result comes to 0.0357, which means that that's the number that represents the density of the wolf population in this North American national park.
