a landscape architect plans to enclose a 3000 square foot rectangular region in a botanical garden. she will use shrubs costing 25$ per foot along 3 sides and fencing costing 15$ along the fourth. write a function that gives the architect's total cost as a function of the length of one of the sides of the garden.
