12. In setting up a kanban control system, you need to determine the number of kanban card sets needed. If the average number of units demanded is 1,000 per hour, the lead time to replenish the order for this item is 10 hours, the container size is 5 units, and the safety stock is estimated to be 5% of the expected demand, what is the number of kanban card sets needed?
