Your research shows that the expected demand during lead time for a particular component is 150 per hour. You estimate the safety stock should be set at 25% of the demand during lead time. The tote trays used as containers can hold 8 units of stock and the lead time it takes to replenish an order is 2 hours. Which of the following is the number of Kanban card sets necessary to support this situation?
