The hardness of the blend = weighted average of hardness of oils in the blend, must be between 3.0 and

The company's blending plant has a monthly capacity for processing:
at most 150 liter of corn, peanut, and coconut oils combined
at most 100 liter of sesame and sunflower oils combined
At the start of the 3-month period assume that there are 300 liters of each kind of vegetable oil in
storage. The plan must provide for the same quantities of each oil in storage at the end of the 3-month
period. For each oil, the storage capacity is 500 liters; the cost of keeping the oil in storage from one
month to the next is P80/liter.
The amount of cooking oil produced = 0.96x(sum of the amounts of vegetable oils blended).
Given the product's popularity, all the cooking oil that is produced in a month can be sold in that month
itself at a price of P290/liter. It is required to formulate a 3-month plan that gives the amount of each
vegetable oil to purchase each month, the amount of cooking oil to produce each month, and the amount
of each vegetable oil to hold over in storage for the succeeding month.
