- The president of Value Filters became very enthusiastic about using EOQs to plan the sizes of her production runs, and instituted lot sizing based on EOQ values before she could properly estimate costs. For one particular filter line, which had an annual demand of 1,800 units per year and which was valued at $2.40 per unit, she assumed a holding cost based on a 30 percent annual interest rate and a setup cost of $100. Some time later, after the cost accounting department had time to perform an analysis, it found that the appropriate value of the interest rate was closer to 20 percent and the setup cost was about $40. What was the additional average annual cost of holding and setup incurred from the use of the wrong costs?arrow_forwardRadovilsky Manufacturing Company, in Hayward, California, makes flashing lights for toys. The company operates its production facility 300 days per year. It has orders for about 12,300 flashing lights per year and has the capability of producing 100 per day. Setting up the light production costs $51. The cost of each light is $0.95. The holding cost is $0.05 per light per year.arrow_forwardThe Kirei-Hana Japanese Steak House in San Francisco consumes 3,000 pounds of sirloin steak each month.Yama Hirai, the new restaurant manager, recently completed an MBA degree. He learned that the steak was replenished using an EOQ value of 2,000 pounds. The EOQ value was computed assuming an interest rate of 36 percent per year. Assume that the current cost of the sirloin steak to the steak house is $4 per pound.a. What is the setup cost used in determining the EOQ value? Mr. Hirai received an offer from a meat wholesaler in which a discount of 5 percentwould be given if the steak house purchased the steak in quantities of 3,000 pounds or more.b. Should Mr. Hirai accept the offer from the wholesaler? If so, how much can be saved?c. Because of Mr. Hirai’s language problems, he apparently misunderstood the offer. In fact, the 5 percent discount is applied only to the amounts ordered over 3,000 pounds. Should this offer be accepted, and if so, how much is now saved?arrow_forward
- The Ambrosia Bakery makes cakes for freezing and subsequent sale. The bakery, which operates five days a week,52 weeks a year, can produce cakes at the rate of 116 cakesper day. The bakery sets up the cake-production operationand produces until a predetermined number (Q) have beenproduced. When not producing cakes, the bakery uses itspersonnel and facilities for producing other bakery items.The setup cost for a production run of cakes is $700. Thecost of holding frozen cakes in storage is $9 per cake peryear. The annual demand for frozen cakes, which is constant over time, is 6000 cakes. Determine the following:a. Optimal production run quantity (Q)b. Total annual inventory costsc. Optimal number of production runs per yeard. Optimal cycle time (time between run starts)e.

Cooler Corporation requires a 12% annual rate of return on investment. In addition, relevant carrying costs for insurance, material-handling, and breakage are $0.40 per unit per quarter, whereas warehousing rental cost is $12,000 per month. Relevant costs per purchase order are $144.00. Purchasing manager’s salary is $80,000 per year. Required: Calculate Cooler’s EOQ for CK55. Calculate Cooler’s total ordering and carrying costs.
