Bartran Company assembles ink cartridges. Each finished cartridge has three child items: a plastic case, a label and several ounces of ink. Lead time on assembling a finished cartridge is 2 days, while the lead time for procuring new plastic cases is 1 day, although the lead time is 5 days for procuring new labels and 2 days for procuring more ink. Assuming that all the assumptions of an MRP bill of materials is true, how long would it take Bartran to create at least one finished ink cartridge if it started with nothing in stock?
