2) Apply. The population density of these grasshoppers is one indicator of whether or not they are considered a pest and are capable of causing damage to crops and plant life. Normally, if these grasshoppers have a population density of 0-3 grasshoppers per
square meter, they don't pose a significant threat. Find the population density of these grasshoppers per square meter. If one acre
is cool to 4,047 square meters, then on average, how many grasshoppers would be found in one square meter?
