Suppose that you are the manager of a production department that
uses 2400 boxes of rivets per year. The supplier quotes you a price
of $9.50 per box for an order size of 199 boxes or less, a price of
$9.00 per box for orders of 200 to 499 boxes, and a price of $8.00
per box for an order of 500 or more boxes. You assign a holding
cost of h=20 percent of the price to this inventory. What...
