The offshore facility is D = 4 miles at sea and L = 8 miles along the shoreline from the power plant. It costs $ 50,000 per mile to lay a power line underground and $ 90,000 per mile to run the line underwater. How much of the power line should be run underground, and how much underwater to minimize the overall costs?
