Final answer:
The reorder point for the corner store is 250 cartons, calculated based on the lead time demand of 50 cartons, and a safety stock of 100 cartons.
Step-by-step explanation:
The reorder point for the corner store is calculated by considering the lead time in days for an order to arrive and the daily demand of milk cartons. Since it's mentioned that the monthly demand is 500 cartons, we can calculate the daily demand by dividing 500 cartons by 30 days (assuming an average month), which gives us approximately 16.67 cartons per day. Given the lead time of 3 days for delivery, you would multiply this daily demand by the lead time (16.67 cartons/day * 3 days = 50.01, rounded to 50 cartons). Lastly, the store wants to maintain a safety stock of 100 cartons at all times. Therefore, the reorder point would be the sum of the lead time demand plus the safety stock, which equals to 150 cartons (lead time demand) + 100 cartons (safety stock) = 250 cartons.
