The demand for ice cream during the three summer months (June, July, and August) at All-Flavours Parlor is exstimated at 500,600, and 400 20-gallon cartons, respectively. Two wholesalers, 1, and 2 supply All-Flavours with its ice cream. Although the flavours from the two suppliers are different, they are interchangeable. The maximum number of cartons either supplier can provide is 100 per month. Also, the price the two suppliers charge change from one month to the next according to the following schedule: Price per carton in month June July August Supplier 1 $100 $110 $120 Supplier 2 $115 $108 $125 To take advantage of price fluctuation, Al-Flavors can purchase more than is nexxded for a month and store the surplus to satisfy the demand in a later month. The cost of refrigerating an ice cream carton is $5 per month. It is realistic in the present situation to assume that the refrigeration cost is a function of the average number of cartons on hand during the month.
