One unit of solution A consumes 5 unit of raw inaterial i and.6 unit of raw material II, and one vnit of solution Buscs .S unit of raw material I and .4 unit of raw material II. The proits per unit of solutions A and B are $8 and 510. sespectively. The daily demand for solution A lies between 30 and 150 units, and that for solution B between 40 and 200 units. Find the optimal production amounts of A and B 10. In the Mr-and-Pa grocery store, shelf space is limited and must be used effectively to in- crease profit. Two cereal items. Grano and Wheatie, compete for a total shelf space of 60 Ft? A box of Grano occupies 2 ft and a box of Wheatie needs. 4 it? The maximum daily demands of Grano and Wheatic are 200 and 120 boxes, respectively. A box of Grano nets $1.00 in profit and a box of Wheatie $1.35. Ma-and-Pa thinks that because the unit profit of Wheatie is 35% higher than that of Grano. Wheatie should be allocated
