E7-7 Riggs Company purchases sails and produces sailboats. It currently produces 1,200 sailboats per year, operating at normal capacity, which is about 80% of full capacity. Riggs purchases sails at $250 each, but the company is considering using the excess capacity to manufacture the sails instead. The manufacturing cost per sail would be $100 for direct materials, $80 for direct labor, and $90 for overhead. The $90 overhead is based on $78,000 of annual fixed overhead that is allocated using normal capacity.
The president of Riggs has come to you for advice. “It would cost me $270 to make the sails,” she says, “but only $250 to buy them. Should I continue buying them, or have I missed something?”
E7-11 Kirk Minerals processes materials extracted from mines. The most common raw material that it processes results in three joint products: Spock, Uhura, and Sulu. Each of these products can be sold as is, or each can be processed further and sold for a higher price. The company incurs joint costs of $180,000 to process one batch of the raw material that produces the three joint products. The following cost and sales information is available for one batch of each product.
E8-2 Eckert Company is involved in producing and selling high-end golf equipment. The company has recently been involved in developing various types of laser guns to measure yardages on the golf course. One small laser gun, called LittleLaser, appears to have a very large potential market. Because of competition, Eckert does not believe that it can charge more than $90 for LittleLaser. At this price, Eckert believes it can sell 100,000 of these laser guns. Eckert will require an investment of $8,000,000 to manufacture, and the company wants an ROI of 20%.
