A certain township consists of a 5-hectare industrial park and a 24-hectare neighborhood. The total number of trees in the township is 4,529. The 5x+24y = 4,529 equation represents this situation. Which of the following is the best interpretation of x in this context?
Correct answer: A (parsed from the explanation — this source omits an answer key for this item)
Explanation
Choice A is correct. It’s given that a certain township consists of a 5-hectare 24 industrial park and a -hectare neighborhood and that the total number of trees 4,529 5 +24 =4,529 in the township is . It’s also given that the equation x y represents this situation. Since the total number of trees for a given area can be 44 SAT PRACTICE TEST #8 ANSWER EXPLANATIONS SAT ANSWER EXPLANATIONS n MATH: MODULE 2 determined by taking the size of the area, in hectares, times the average number of trees per hectare, the best interpretation of 5x is the number of trees in the 24 industrial park and the best interpretation of y is the number of trees in the neighborhood. Since 5 is the size of the industrial park, in hectares, the best interpretation of x is the average number of trees per hectare in the industrial park. Choice B is incorrect and may result from conceptual errors. Choice C is incorrect and may result from conceptual errors. Choice D is incorrect and may result from conceptual errors.
