Silver is purchased from a mining operation in Argentina, La Tierrra. 1 pound of grade B silver costs $50 and 1 pound of grade A silver costs $75. Purchases of 100 pounds or more are subject to a 10% discount. In addition, cash purchases (made in Argentia's currency) receive an additional 5% discount. La Tierra pays for all shipping at a rate of $5 per pound. Duties to import silver into Canada are about 15% of the declared value of each shipment. Lucky has decided to use grade B silver and to take advantage of both of the offered discounts.

Each finished medallion must weigh one tenth of a pound. First, any impurities in the silver must be removed. On average this results in the loss of about 5% of the weight of the silver. After that, the medallions are formed by melting the silver and pouring it into round forms. Spillage during this process amounts to about 3% of the molten silver. Finally the design must be stamped onto the face of the medallion. During this process, an average of 2% of the medallions break and must be discarded.

During the month of April, Lucky purchased 6,000 pounds of silver at a total cost of $295,300. 3,900 pounds were used to produce 30,000 medallions. A total of 6,680 DL hours were worked on silver medallions. The associated cost was $191,240. Overhead is applied on the basis of machine hours.
