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 $2.50 a pound to make and sells for $3.70 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 $4.90 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 $2.20 per jar. Variable selling costs are $0.40 per
jar. If the decision were made to cease production of the silver polish $8300 of Mixing Department fixed costs could be avoided. Zytel has limited production
capacity for Grit 337 but unlimited demand for the cleaning powder.

Calculate the minimum number of jars of silver polish that would have to be sold to justify further processing of Grit 337. (Round your intermediate calculation to 2 decimal places and final answer to the nearest whole number.)
