Plano Products manufactures a wide variety of chemical compounds and liquids for industrial uses. The standard mix for producing a single batch of 100 liters of its biggest selling product is as follows Quantity (in liters) Cost (per liter) 12 24 Total Cost $ 180 720 Input Chem-A Chem-E Chem-C 20 60 45 125 $1,980 There is a standard 20 percent loss in liquid volume during processing due to evaporation. The finished liquid is put into 10-liter containers for sale. Thus, the standard material cost for a 10-liter container is $198($1,980+100 liters) x10 liters per container]. The actual quantities of direct materials and the cost of the materials placed in production during September were as follows (materials are purchased and used at the same time) Input Quantity (in liters) 16,960 50,400 37,040 104,400 Total Cost $ 149,248 607,320 898,220 Chem-A Chem-B Chem-C $1,654,788 A total of 8,000 containers (80,000 liters) were produced during September. Required Calculate the total direct material variance for the liquid product for the month of September and then further analyze the total variance into a. & b. Materials price and efficiency variances, materials mix and yield variances. (Do not round intermediate calculations. Round Standard mix values" to 2 decimal places. Indicate the effect of each variance by selecting "F" for favorable, or "U" for unfavorable. If there is no effect, do not select either option.)
