Christine's Chronographs makes two models of a high-end watchthe model 94 and the model 101. Both models go through a special polishing step that requires the use of the single polishing machine at the company. The price and costs of the two models appear as follows.

Price per watch	$	5,100		$	9,700
Variable cost per watch	$	2,600		$	5,800
Polishing hours per watch		2			3

The polishing machine used for both models has a capacity of 33,600 hours annually. Fixed manufacturing costs are $7,800,000 annually.

Required:

Freeflight Airlines is presently operating at 70 percent of capacity. Management of the airline is considering dropping Freeflight's routes between Europe and the United States. If these routes are dropped, the revenue associated with the routes would be lost and the related variable costs saved. In addition, the company's total fixed costs would be reduced by 20 percent.

Segmented income statements for a typical month appear as follows (all amounts in millions of dollars):

Routes	Within U.S.				Within Europe				Between U.S. and Europe
Sales	$	3.28			$	2.77			$	2.82
Variable costs		1.26				0.91				1.71
Fixed costs allocated to routes		1.68				1.27				1.37
Operating profit (loss)	$	0.34			$	0.59			$	(0.26	)

Required:

a. Prepare a differential cost schedule.
