d) What is the annual total cost if the optimal quantity is ordered?
1. Calculate Economic Order Quantity (EOQ), number of orders, annual ordering costs, annual carrying costs and total inventory costs from the following: Annual consumption: 6000 units ; Cost of placing one Order: RO 60 Carrying cost per unit: RO 22. Find out the EOQ, Annual ordering cost and annual holding cost from the following information. The demand is 19500 units per year, holding cost is RO 4 per unit for a year and ordering cost is RO 25 order. 3. Find out the ordering cost from the following information, Annual demand is 240 units, holding cost RO 4 per unit for a year and EOQ is 60 units.

- Economic Order Quantity (EOQ) is a method used to calculate the ideal quantity to order. The underlying concepts of EOQ is the balance between ordering cost and holding cost. perform two calculations: A = annual demand = 20,000 Cp = Cost of an order which includes preparing and following up the order = $100.00 Ch = Unit inventory cost per year or item cost (P) $100 times annual carrying cost rate (r) (25%) 1. Use an excel file to calculate the EOQ order. Follow the video provided:arrow_forwardAbey Kuruvilla, of Parkside Plumbing, uses 1,200 of a certain spare part that costs $25.00 for each order, with an annual holding cost of $24.00. a) Calculate the total cost for order sizes of 25, 40, 50, 60, and 100 (round your response to the nearest whole number). b) What is the economic order quantity? units (round your response to the nearest whole number). Order Size 25 40 50 60 100 Total Cost ($)arrow_forwardA car rental agency uses 96 boxes of staples a year. The boxes cost $5 each. It costs $10 to order staples, and it costs $0.80 to hold a box of staples in inventory for 1 year. A.) How many boxes of staples should the car rental company order each time it needs staples, to minimize the combined ordering and holding costs for staples? B.) Using the order size that minimizes the car rental agency’s combined ordering and holding costs for staples, how long will a single order of staples last the agency, before it must receive more staples? (Assume there are 52 weeks in the year for the car rental agency.) C.) Using the order size that minimizes the car rental agency’s combined ordering and holding costs for staples, how much does the car rental agency actually spend on holding costs for staples each year?arrow_forward
- A manufacturer of exercise equipment purchases the pulley section of the equipment from a supplier who lists these prices: Less than 1000 $5.00 each 1000 to 3999 $4.95 each 4000 to 5999 $4.90 each 6000 or more $4.85 each Ordering costs are $50, annual carrying costs per unit are 40 percent of purchase cost, and annual usage is 4900 pulleys. Determine the order quantity that will minimize total cost.arrow_forwardThe XYZ Company has an annual sale of 20,000 television sets. each inventory item has a value of P2,500.00.

Carrying costs are $4 per unit per year. A. use the formula for Economic Order Quantity to find out how many reams of paper they should purchase in each order. B. how many orders should they place over the year?arrow_forwardthe economic order quantity (see Chapter 12 for EOQformulas) for its halogen lamps. It currently buys all halogenlamps from Specialty Lighting Manufacturers in Atlanta.
