QUESTION 1:A confectioner buys plastic boxes in bulk and uses them to pack chocolates. The annual requirement of these boxes is 1,200, and each box costs $30. The ordering and carrying costs are $10 per order and 20%, respectively. The supplier from whom the confectioner purchases these boxes sells them only in lots of 25, that is, you only purchase quantities in multiples of 25 boxes.(a) How many boxes should the confectioner order so as to minimise inventory total stocking costs?(b) If the supplier offers 2% discount on the cost of each box when the purchases are in quantities of 300 at a time, should the confectioner accept this offer?(c) Suppose the supplier has decided that instead of the 2% discount offer the following price breaks will be used:ORDER QUANTITY COST PER BOXLess than 100 $30.00100 to 199 $29.75200 or more $29.60What order quantity should the confectioner make?

- Question 3: Powered by Koffee (PBK) is a new campus coffee store. PBK uses 50 bags of whole bean coffee every month, and you may assume that demand is perfectly steady throughout the year. PBK has signed a yearlong contract to purchase its coffee from a local supplier, Phish Roasters, for a price of $25 per bag and an $85 fixed cost for every delivery independent of the order size. The holding cost due to storage is $1 per bag per month. PBK managers figure their cost of capital is approximately 2 percent per month. What is the optimal order size, in bags? (Round the answer to 2 decimal places.) Given your answer in (a), how many times a year does PBK place orders? (Round the answer to the nearest whole number.) Given your answer in (a), how many months of supply of coffee does PBK have on average? (Round the answer to 2 decimal places.)
