SAT Question 3c03cbd8: Linear Equations In Two Variables answer and explanation with Desmos solution

Choice A is correct. It's given that a certain township consists of a $5$ -hectare industrial park and a $24$ -hectare neighborhood and that the total number of trees in the township is $4,529$. It's also given that the equation $5x+24y=4,529$ represents this situation. Since the total number of trees for a given area can be 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 industrial park and the best interpretation of $24y$ 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.
