(Q1 - Q6) Spring Water The demand for coconut water at SLC Walmart is 600 gallons per week. The setup cost for placing an order to replenish inventory is $25. Coconut water loses its freshness when stored, and SLC Walmart incurs an annual holding cost of $2.6/g allon. Assume that there are 52 weeks a year.

Sarah's annual holding cost is $1.825 per kg of palm oil. Assume there are 365 days a year. Question 7 0/0.25pts If Sarah wants to minimize inventory holding and ordering costs, how much Palm oil should she purchase with each order (in kgs )? Question 8 0/0.25 pts What is the daily cost of ordering and holding when EOQ is ordered? Again, assume that Sarah needs 1,000kgs of Palm oil per day.

(Note that the daily cost of Palm oil is determined by the daily demand multiplied by the selling price.) (Q1 - Q6) Spring Water The demand for coconut water at SLC Walmart is 600 gallons per week.
