Montreal Hardware Co. is making a make-or-buy decision. The market feedback shows that the optimal price for this item is $10 each. If the item is outsourced to Laval Hardware Co, there is virtually no cost other than the $6 per unit that they would pay Laval Hardware Co. Internally, they have two choices. Process A requires an investment of $120,000 for design and equipment, but it results in a $4 per unit cost. Process B requires only a $100,000 investment, but its per unit cost is $5.
