Ajax Manufacturing produces a single product, which takes 8.0 pounds of direct materials per unitproduced. Assume that it is currently at the end of the first quarter of the year, and there are 50,000pounds of material on hand. The company’s policy is to maintain an end-of-quarter inventoryof materials equal to 25 percent of the following quarter’s material requirements for production.How many units of product were produced in the first quarter of the year? Under the assumptionthat production will increase by 10 percent in the second quarter, what are the direct materialsrequirements (in pounds) for planned production in the second quarter?

Southwood Furniture Company is a U.S.-based furniture manufacturer that offshored all of its actual manufacturing opera- tions to China about a decade ago. It set up a distribution center in Hong Kong from which the company ships its items to the United States on container ships. The company learned early on that it could not rely on local Chinese freight forwarders to arrange for sufficient containers for the company's shipments, so it contracted to purchase containers from a Taiwanese manufacturer and then sell them to shipping companies at the U.S. ports the containers are shipped to. Southwood needs 715 containers each year. It costs $1200 to hold a container at its distribution center, and it costs $6000 to receive an order for the containers. Determine the optimal order size, min- imum total annual inventory cost, number of annual orders, and time between orders.arrow_forwardAnswer 12.8arrow_forward
