The city needs at least 10 million gallons/day and can get it either from it's own reservoir or from a pipeline in a neighboring town.The reservoir can supply up to 5 million gallons/day.

The water from the reservoir costs $300 per million gallons.  The water from the pipeline costs $500 per million gallons.  What would you advise the city manager to do?
