A drilling 12 miles off the coast will be connected to a coastal refinery, 20 miles below the perforation line. The underwater pipeline cost $ $50.000 per mile. Whereas the land, cost $30.000 per mile. What is the combination of the two types of products that will provide the least expensive connection?

Do a search for "pipeline" in the forum. There's a few threads with puzzles like this.
