A neighborhood consists of a 2-hectare park and a 35-hectare residential area. The total number of trees in the neighborhood is 3,934. The equation 2x + 35y = 3,934 represents this situation. Which of the following is the best interpretation of x in this context?
Correct answer: A. The average number of trees per hectare in the park
- A. The average number of trees per hectare in the park
- B. The average number of trees per hectare in the residential area
- C. The total number of trees in the park
- D. The total number of trees in the residential area
Explanation
The correct answer is that x represents the average number of trees per hectare in the park. The equation 2x + 35y = 3,934 indicates that 2x is the number of trees in the park, calculated by multiplying the park's area (2 hectares) by the average number of trees per hectare (x). Thus, x is the average number of trees per hectare in the park. The other options are incorrect because they either misidentify the role of x in the equation or assign x to the wrong area.
