Bruno Fruscalzo decided to start a small production facility in Sydney to sell gelato to the local restaurants. His local milk supplier charges $0.50 per kg of milk plus a $20 delivery fee (the $20 fee is independent of the amount ordered). Bruno’s holding cost is $0.03 per kg per month. He needs 9000 kg of milk per month.
a)Suppose Bruno orders 9000 kg each time. What is his average inventory (in kg)?
b)Suppose Bruno orders 7000 kg each time. How many orders does he place with his supplier each year?
c)How many kg should Bruno order from his supplier with each order to minimize the sum of the ordering and holding costs?
d)If Bruno’s storage vessel can hold only 3000 kg of milk, what would be Bruno’s minimum annual ordering and holding costs?
