In the J & K grocery store, shelf space is limited and must be used effectively to increase profit. Two cereal items, Grano and Wheatie, compete for a total shelf space of 79ft^2. A box of Grano occupies 0.2ft^2 and a box of Wheatie needs 0.4ft^2. The maximum daily demands of Grano and Wheatie are 280 and 127 boxes, respectively. A box of Grano nets $1.00 in profit and a box of Wheatie $1.47.
