The number of apples produced by a single tree in an orchard is a linear function of the number of trees in the orchard. An orchard of 100 trees yields approximately 150 apples per tree. When the number of trees is increased to 130, the yield per tree is approximately 60 apples. Write a linear function to model the relationship between the number of trees in the orchard and the number of apples per tree.
