(c) A Mine Company owns two different mines that produce an ore (metal) which, after being crushed, is graded into three grades: high, medium and low. The company has been contracted to provide a smelting plant with 50 tons of high -grade, 40 tons of medium -grade and 60 tons of low-grade ore per week. The two mines have different operating patterns/system as detailed below
Mine Cost per day ($ 000') Production (tons/day)
High Medium Low

Y 190 3 4 6
Suppose that mines are not operated in the weekend. Formulate as LP model to determine days per week should each mine be operated to fulfill the smelting plant contract while minimizing the weekly operating cost? (Do not solve).
