Zytel 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\mathrm{.}80$ a pound to

make and sells for $$4\mathrm{.}00$ 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\mathrm{.}80$ per jar. This further processing requires $\frac{1}{4}$ pound of Grit $337$ per jar. Costs of other ingredients, labor, and variable overhead

associated with this further processing amount to $$2\mathrm{.}20$ per jar. Variable selling costs are $$0\mathrm{.}30$ per jar. If the decision were made to

cease production of the silver polish, $$8,700$ of Mixing Department fixed costs could be avoided. Zytel has limited production capacity

for Grit $337,$ but unlimited demand for the cleaning powder.

Required:
