The document presents an Economic Order Quantity (EOQ) model with a weekly demand of 100 units and an order quantity of 1200 units. At the beginning of week 1, there is an initial inventory of 1200 units with no outstanding orders. The goal is to determine the inventory level at the end of week 5.

1. Suppose we have an EOQ model as follows:
[1] weekly demand = 100 units/week
[2] order quantity = 1200 units/order
[3] At the beginning of week 1, there are 1200 units in
inventory
and there is no outstanding order (or shipment).
What is the inventory level at the end of week 5?
