Susan's Plastics, Inc., manufactures a line of office desk accessories. The company's newest and most popular product is a plastic paper holder for holding the paper up while working at the computer. Production began on February 1, 2019. Plastic is poured into molds to form the product, and the entire process takes place in the Molding Department. After the liquid plastic is poured (signifying the beginning of the process), the molds must be cooled slowly before the paper holder is separated from the mold. Statistics for 2019 are shown below.
