Plastomer, Inc., specializes in the manufacture of high-grade plastic film used to wrap food products. Film is rejected and scrapped for a variety of reasons (e.g., opacity, high carbon content, incorrect thickness or gauge, scratches, etc.). During the past month, management collected data on the types of rejects and the amount of scrap generated by each type. The following table presents the results:
