Problem 1 Creative Design makes intricate jewelry out of precious metal. The company is introducing a new line and needs to select a manufacturing process. Three options are available. Option I involves using a mold to mass produce the design for pendants, earrings, and bracelets. Option II laser cuts the design from a block of metal using a pattern directed by the software. Option III builds the design out of metal powder (gold, silver, and bronze) via a 3D printer. The company is uncertain about the demand for the new design. The cost data for each manufacturing option are given in the following table. Manufacturing Option Fixed Cost Variable Cost per Unit 1 $10,000 $10 II $5,000 $30 III $3,000 $50 a.
