Determine the indicated function.A rectangular garden is to be surrounded on three sides by a fence costing $5 per foot and on one side by a stone wall costing $20 per foot. Let x be the length of the side with the stone wall, and let y be the length of each of the other three sides. Express the cost C of enclosing the garden as a function of the length and width.
A. C(x, y) = 20x - 15y B. C(x, y) = (20x)(15y) C. C(x, y) = 15x + 20y D. C(x, y) = 20x + 15y
