Same machine:

Annual operating savings $2000

What is the simple (annual or accounting) rate of return?

Calculate the minimum acceptable transfer price!

Division A capacity is 100,000 units.

External demand is 100,000 units at a selling price of $30.

Variable cost per unit is $16.

Fixed cost per unit is $9.

Division B requests 10,000 units from Division A (currently purchasing externally for $29).
