Exercise 14-40 Joint Products; Relevant Costs; Cost-Volume-Profit Analysis (LO 14-4, 14-6) 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 $160 a pound to make and selts for $280 a pound. A small portion of the annual production of this product is retained for further processing in the Moing Department, where it is combined with several other ingredients to form a paste, which is marketed as a siver polish selling for $5.50 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 $2.40 per jar, Variable selling costs are $0.50 per jar. If the decision were made to cease production of the silver polish, $8,700 of Mixing Department fixed costs could be avolded Zytel has limited production capacity for Grit 337, but unlimited demand for the cleaning powder. Required: Calculate the minirnum number of jars of silver polish that would have to be soid to justify further processing of Grit 337. (Round your intermediate calculations to 2 decimal places and final answer to the nearest whole number.)
