4. What inventory method is used to value inventories? Does this method reflect current cost at year-end?

The next task is to provide the optimum number of shoelaces to order, using appropriate cost balancing. The economic order quantity (EOQ) is the order amount that allows for an optimum level of materials at the lowest cost possible. There is a demand ofr 300,000 shoelaces per year. The setup cost is $125 per order. There is a $.10 holding cost per unit. The optimal order quantity recommended is 27,386.13 shoelaces per order, with a maximum inventory of 27,386.13. This means that we will order just the amount of shoelaces needed to fulfill current production orders. The average inventory is 13,693.06 shoelaces. There will be approximately 10.95 orders per year. The annual setup cost is $1,369.31, and the annual holding cost is $1,369.31. This makes the total cost per year $2, 738.61. This decision tool allows us to calculate the correct amount needed per order to ensure that we are lowering operating and holding costs, while keeping production properly stocked.

12. If 12,500 units are produced, what is the total amount of manufacturing overhead cost incurred to support this level of production? What is the total amount expressed on a per unit basis?

The calculations required for question 1 are not massive (it takes more thinking than pencil‐pushing). Working those calculations will help solidify your understanding of the relationship between inventory and cost of goods sold in a manufacturing company. You’ll know you’re on the right track if you conclude that the answer to part b(3) is “no effect.”

Peter’s Peripherals assembles multimedia upgrade kits --- sets of components for adding sound and video to desktop computers. The demand for their kits for the next four quarters is estimated in the table below. Unit manufacturing cost for each kit is $160. Holding costs on each kit is $80 per quarter. Any kit that must be delivered late is assessed a backorder cost of $120. Each worker is capable of finishing 10 kits per quarter. If the company chooses to vary work force levels, it will incur costs of $400 for each additional worker; $600 for each termination. The company currently has 28 employees.

The cost of carrying inventories has been calculated using the current cost of bank loans (see Table 2). Do you think this is the appropriate rate? Explain, and in your answer consider both WACC and tax effects.

In line with our objective, we proposed two different models both resulted in reducing the total cost. Proposed scenarios are:

30. The manager of the local National Video Store sells videocassette recorders at discount prices. If the store does not have a video recorder in stock when a customer wants to buy one, it will lose the sale because the customer will purchase a recorder from one of the many local competitors. The problem is that the cost of renting warehouse space to keep enough recorders in inventory to meet all demand is excessively high. The manager has determined that if 90% of customer demand for recorders can be met, then the combined cost of lost sales and inventory will be minimized. The manager has estimated that monthly demand for recorders is normally distributed, with a mean of 180 recorders and a standard deviation of 60. Determine the number of recorders the manager should order each month to meet 90% of customer demand.

Although the shelves are selling well, the total profit of the company is a concern. An engineer suggested that the current production of model S should be cut back because Model S shelves are sold for $1800 per unit but their costs are $1839. Therefore, company is losing money on each one. But

Each week there are 300 pounds of material 1; 400 pounds of material 2; and 200 hours of labor. The output of product A should not be more than one-half of the total number of units produced. Moreover, there is a standing order of 10 units of product C each week.

Gioe Melaney is the general director of Southern Toro – a subsidiary company included in the distribution system of Toron Coporation in Galveston, Taxas.

Compute the projected profit for the order quantities suggested by the management team under three scenarios: worst case in which sales = 10,000 units, most likely case in which sales = 20,000 units, and best case in which sales = 30,000 units.

Dong Hai Supply Annual Inventory Carrying Cost = 0.322 * ((24,037*80.11) + (24,037/551)*182) = $622,601.

In, 8 hours a day, the company can produce 60 * 8 * (1/0.5) = 960 shirts, which is the current production capacity. But it needs to produce only 800 shirts.

Consolidated Company makes cardboard boxes. During the most recent accounting period Consolidated paid $60,000 for raw materials, $48,000 for labor, and $52,000 for overhead costs that were incurred to make boxes. Consolidated started and completed 400,000 boxes. Based on this information, what is the average manufacturing cost per box?
