You are thinking of adding the new food product to the store for resale. You are sure that, in the month, minimum demand for product will be 6 units, where as maximum demand will be 8 units. (Unfortunately, new product has one-month shelf life and is thought to be waste at the end of month.) You will pay $60/unit for the new product while you plan to sell product at a $40/unit profit. Evaluated demand for the new product in any given month is six units(p=0.1), seven units(p=0.4), and eight units(p=0.5). Using EMV analysis, how many units of new product must be bought for resale?
