Barbour Electric is considering the introduction of a new product. This product can be produced in one of several ways: a) using the present assembly line at a cost of $25 per unit, b) using the current assembly line after it has been overhauled (at a cost of $10,000) with a cost $22 per unit; and c) on an entirely new assembly line (costing 30,000) designed especially for the new product with a per unit cost of $20. Barbour is worried, however, about the impact of competition. If no competition occurs, they expect to sell 15,000 units the first year. With competition, the number of units sold is expected to drop to 9,000. At the moment, their best estimate is that there is a 40% chance of competition. They have decided to make their decision based on the first year sales.
