The Westcoast Company produces footballs and currently uses a machine that could be sold in the market for $15,000. The current annual variable expenses are $80,000 for machine running costs and the current machine has a remaining useful life of 5 years. The original cost of the current machine was $72,000 and the remaining book value is $60,000. A replacement machine would cost the company $90,000 and annual variable expenses for running the machine would be $100,000. The new machine also has an expected future life of 5 years. Sales are expected as $200,000 per year with the old machine and $250,000 per year with the new replacement. Fixed costs other than depreciation are $70,000 per year in both cases (ignore the time value of money).

	a.	The manager should keep the old machine because the net benefit is $45,000.
	b.	The manager should replace the old machine because the net benefit is $45,000.
	c.	The manager should replace the old machine because the net benefit is $75,000.
	d.	The manager should keep the old machine because the net benefit is $57,000.
	e.	The manager should replace the old machine because the net benefit is $87,000.
