Juarez Corporation produces cleaning compounds and solutions for industrial and household use. While most of its products are processed independently, a few are related. Grit 337, a coarse cleaning powder with many industrial uses, costs $2.00 a pound to make and sells for $3.20 a pound. A small portion of the annual production of this product is retained for further processing in the Mixing Department, where it is combined with several other ingredients to form a paste, which is marketed as a silver polish selling for $5.30 per jar. This further processing requires 1/4 pound of Grit 337 per jar. Costs of other ingredients, labor, and variable overhead associated with this further processing amount to $2.10 per jar. Variable selling costs are $0.50 per jar. If the decision were made to cease production of the silver polish, $8,900 of Mixing Department fixed costs could be avoided. Juarez has limited production capacity for Grit 337, but unlimited demand for the cleaning powder.
