A rectangular billboard must have an area of 48 square meters. The cost of the material for the border (perimeter) is $20 per meter, while the cost for the interior (area) is $5 per square meter. If the width of the billboard is constrained to be between 4 and 12 meters, what width minimizes the total cost?
