A uranium processor has two sources of uranium ore, Albuquerque and Bainsville. In order to keep his plant running, at least three tons of ore must be processed each day. Ore from Albuquerque costs $20 per ton to process. and ore from Bainsville costs $10 per ton to process. Costs must be kept to Tess than $100 per day. Moreover, a business arrangement requires that the amount of ore from Bainsville cannot exceed twice the amount of ore from Albuquerque. Ore from Albuquerque yields 3 lbs of uranium per ton, and ore from Bainsville yields 2 Ibs of uranium per ton. Subject to these constraints. how many tons of ore from each source must be processed each day to maximize the amount of uranium extracted?
