As a manager, you must choose between two options for new production equipment:

Option A: Machine A will increase fixed costs by a substantial margin but will produce greater sales volume at the current price.

Option B: Machine B will only slightly increase fixed costs but will produce considerable savings on variable cost per unit. No additional sales are anticipated if Machine B is selected.

How could you go about analyzing which machine is the better investment for the company in terms of both net operating income and break-even?
