Star Coffee sells three coffee blends (in 1-lb packages): PremiumCream, DeliSoft, and ValleyTaste. These blends are obtained by carefully mixing coffee beans imported from various countries, as presented below. For example, 1 lb of PremiumCream is the result of blending 70% Ethiopian and the remaining 30% Indonesian beans (no Colombian or Brazilian beans). Due to contracts with suppliers, minimum monthly bean consumptions must be satisfied. Due to logistics/capacity, monthly bean consumptions cannot exceed maximum monthly amounts as given below. For example, monthlly consumption of Ethipian beans must be at least 200 lb but no more than 1000 lb.
	PremiumCream	DeliSoft	ValleyTaste		Minumum Consumption	Maximum Consumption
	1 lb	1 lb	1 lb		lb	lb
Ethiopian beans	0.7	0.3			200	1000
Indonesian beans	0.3	0.2			100	2000
Colombian beans		0.3	0.8		400	1000
Brazilian beans		0.2	0.2		100	3000
