Mississippi Manufacturing makes a component called B2040. This component is manufactured only when ordered by a customer, so Mississippi keeps no inventory of B2040. The list price is $112 per unit, but customers who place "large" orders receive a 10% discount on price. The customers are manufacturing firms. Currently, the salespeople decide whether an order is large enough to qualify for the discount. When the product is finished, it is packed in cases of 10. If the component needs to be exchanged or repaired, customers can come back within 14 days for free exchange or repair. (Click the icon to view the data.)
