Question II
The PriceRite big box discount center orders printer cartriges from a manufacturer in the Far East.  PriceRite annual demand for the printer cartridges is 6000 units.  Assume that demand is steady, and the lead time is zero.  The fixed cost per order is $200, while the inventory carrying cost is 25%.  The wholesale price is $45 per unit.  The supply firm has just offered PriceRite a quantity discount contract:  if they place an order of at least 2000 units, the price will be $44 per unit.  Build a spreadsheet model to evaluate the quantity discount offer.
