Explanation

Choice A is correct. It’s given that there are $2,358$ raccoons in a $131$ -square-mile area. The estimated population density, in raccoons per square mile, is the estimated number of raccoons divided by the number of square miles. Therefore, the estimated population density of this area is $StartFraction 2,358 raccoons Over 131 square miles EndFraction$ , or $18$ raccoons per square mile.

Choice B is incorrect. This is the number of square miles in the area, not the estimated number of raccoons per square mile in this area.

Choice C is incorrect and may result from conceptual or calculation errors.

Choice D is incorrect and may result from conceptual or calculation errors.
