End item A requires three component parts: B, C, and D. The BOM indicates that for each completed A, 1 unit of B, 2 units of C, and 1 unit of D are required. Current inventory for the four items is as follows: there are 15 As, 40 Bs, 50 Cs, and 15 Ds in stock. If the lead time for all items is 1 week and there are no scheduled receipts for any item, how many units of product A can be delivered to customers at the start of next week (week 2) if you realize now the BOM has been just changed?
