Question content area Part 1 Consider a three-firm supply chain consisting of a retailer, manufacturer, and supplier. The retailer's demand over an 8-week period was 105 units each of the first 2 weeks, 210 units each of the second 2 weeks, 280 units each of the third 2 weeks, and 400 units each of the fourth 2 weeks.

3	210	420
4	210

6	280
7	400	800
