Weekly demand for a VR Headset retailer has a mean of $20$ units. The supplier has a lead time of $15$ weeks. The cost of placing an order to the supplier each time is $$40,$ and annual holding cost for one unit is $20$ percent of the Cost of Goods. Each headset costs the retailer $$1,040.$ Assume $52$ weeks in a year.

Assume there is no variation with a steady demand $($Chapter $12).$

How many orders are we going to place for the year if we order $16$ headsets in each order? Again, assume steady demand and that we're meeting demand.
