Memo

The cost of production report was used to identify the cost per case for each of
the four flavors as shown next.

The preceding table indicates the concentrate per case is less for Grape and Root
Beer than for Cola and Orange. This is because the concentrate supplier charges
a higher price for the more popular flavors. The costs per case for water, sugar,
and bottles are the same for each flavor. However, the costs per case for
changeover are much greater for Grape and Root Beer than for the other two
flavors. In addition, the conversion costs per unit for Grape and Root Beer are
$0.35 higher than for Cola and Orange. These last two cost elements are sufficient
to cause the cost per case of Grape and Root Beer to be greater than Cola and
Orange.

The objective of this exercise is to determine if cost-per-pound trends in paper
stock, conversion, and coating costs are remaining stable over time. The follow-
ing table can be developed from the data:

The cost-per-pound information is determined by dividing the costs by the
pounds transferred out. The yield is determined by dividing the pounds trans-
ferred out by the pounds input.
b. Operator 1 believes that energy consumption is becoming less efficient. The
energy cost is part of the conversion cost. The conversion cost per output
pound has remained constant for the six months. If the energy efficiency were
declining, it would take more energy per pound of output over time. Thus, we
would expect to see the conversion rate per pound increasing if Operator 1
were correct.
