Final answer:
The rate representing the relationship between the number of trees and the area of the park is found by dividing the total trees by the total acreage, resulting in 22.69 trees per acre. Option c is correct.
Step-by-step explanation:
To find the rate that best represents the relationship between the number of trees in the park and the area, we divide the total number of trees by the total area of the park.
Trees per Acre = Total Number of Trees ÷ Total Acres
Trees per Acre = 7,475 trees ÷ 325 acres
Trees per Acre = 22.69 trees per acre
Therefore, the best representation of the rate is 22.69 trees per acre, which corresponds to option c.
