Gaermont Cereal manufactures three types of energy seed combinations that are sold to wholesalers, which in turn sell them at retail expenses. All three types are normal, special and extra and sell at $15, $22 and $35 per pound, respectively. Each mixture requires the same ingredients: peanuts, raisins, coconut, almonds and sunflower seeds. The costs per pound of each of these ingredients are $12, $16, $15, $24 and $20 for peanuts, raisins, coconut, almonds and sunflower seeds, respectively.

The requirements of the mixtures are:

Normal: at least 15% of each ingredient

Special: at least 15% of each ingredient and no more than 30% of any of them

Extra: at least 15% raisins, at least 20% almonds and no more than 25% peanuts

Production facilities make a maximum of 1500 pounds of peanuts, 2200 raisins, 1500 coconut, 3000 almonds and 2800 sunflower seeds available per week. There is also the condition that at least 20% of each type of mixture must be produced. Raise a PL issue to maximize utilities.
