Quizplus · Accepted Answer

The correct number of kanbans can be calculated using the formula: $ \text{Number of Kanbans} = \frac{\text{Demand during lead time} + \text{Safety stock}}{\text{Size of one container}} $. Here, demand during lead time is $2 \text{ days} \times 10 \text{ cakes/day} = 20 \text{ cakes}$, and safety stock is $0.5 \text{ day} \times 10 \text{ cakes/day} = 5 \text{ cakes}$. Thus, $ \frac{20 \text{ cakes} + 5 \text{ cakes}}{1 \text{ cake/container}} = 25 $ kanbans.
