Decision on transfer pricing

Materials used by the Instrument Division of Ziegler Inc. are currently purchased from outside suppliers at a cost of $$359$ per unit. However, the

same materials are available from the Components Division. The Components Division has unused capacity and can produce the materials needed by

the Instrument Division at a variable cost of $$298$ per unit.

Assume that a transfer price of $$341$ has been established and that $34,200$ units of materials are transferred, with no reduction in the Components

Division's current sales.

a$.$ How much would Ziegler Inc.$\text{'}$s total operating income increase?

b$.$ How much would the Instrument Division's operating income increase?

c$.$ How much would the Components Division's operating income increase?
