Sarah’s Organic Soap Company makes organic liquid soap. One of the raw materials for her soaps is organic palm oil. She needs 1,000 kgs of palm oil per day on average, i.e., the demand rate of palm oil is 1,000 kgs per day.

Sarah’s annual holding cost of one kg of palm oil is 25% of the purchase price. Sarah wants to minimize her annual fixed ordering and inventory holding costs, i.e., the EOQ cost per year C(Q).
