1. Suppose that the actual demand for the year is 48,000 packs and that you contracted for 50,000 packs. What is the net profit for the store? 2. If you had had perfect knowledge, you would have contracted for 48,000 rather than 50,000 packs. What would the net profit have been if you had ordered 48,000 packs? Having ordered 50,000 instead, what was the cost of your prediction error? 3. Given an actual volume of 48,000 units, by how much would the average pur- chase cost of the pack have had to rise before you would have been indifferent between having the contract for 50,000 packs and not having the contract?
