would like help understanding how to calculate the attached.

Exercise 14-40 Joint Products; Relevant Costs; Cost-Volume-Prot 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 $2.60 a pound to make and sells for $3.80 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 $6.10 perjar. This further processing requires 1/4 pound of Grit 337 perjar. Costs of other ingredients, labor, and variable overhead associated with this further processing amount to $2.10 perjar. Variable selling costs are $0.40 perjar. If the decision were made to cease production ofthe silver polish, $8,500 of Mixing Department fixed costs could be avoided. Zytel has limited production capacity for Grit 337, but unlimited demand for the cleaning powder. Required: Calculate the minimum number ofjars of silver polish that would have to be sold tojustify further processing of Grit 337. (Round your intermediate calculations to 2 decimal places and nal answer to the nearest whole number.)
