His local milk supplier charges $0.5 per kg of milk plus a $20 delivery fee (that is independent of the amount ordered). Bruno's holding cost is $0.03 per kg per month. He needs 9750kgs of milk per month. a. Suppose Bruno orders 9000kgs each time. What is his average inventory (kgs)? kgs (Round your answer to 1 decimal place.) b. Suppose Bruno orders 8000kgs each time. How many orders does he place orders with his supplier each year? How many kgs should Bruno order from his supplier with each order to minimize kgs the sum of ordering and holding costs? (Do not round intermediate calculations. Round your answer to 2 decimal places.) d. If Bruno's storage vessel can hold only 3250kgs of milk, what would be Bruno's annual ordering and holding costs? (Do not round intermediate calculations. Round your answer to 2 decimal places.) If Bruno's storage vessel can hold only 6000kgs of milk, what would be Bruno's e. annual ordering and holding costs
