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.
There is a standard 20 percent loss in liquid volume during
processing due to evaporation. The finished liquid is put into
13-liter containers for sale. Thus, the standard material cost for
a 13-liter container is $258.96 [= ($1,992 ÷ 100 liters) × 13
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).
A total of 8,300 containers (107,900 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 and materials mix and yield variances. (Do
not round intermediate calculations. Round “Standard mix
values” to 3 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. Enter your answers rounded
to the nearest whole number.)
