Please answer question F. and please tell my Step by Step how you got your answer!

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 $15 delivery fee (that is independent of the amount ordered). Brunos holding cost is $0.03 per kg per month. He needs 8250 kgs of milk per month.
a.	Suppose Bruno orders 10000 kgs each time. What is his average inventory (kgs)?		5,000	kgs
	(Round your answer to 1 decimal place.)
b.	Suppose Bruno orders 6250 kgs each time. How many orders does he place with his supplier each year?		15.8	orders
c.	How many kgs should Bruno order from his supplier with each order to minimize the sum of ordering and holding costs?		2,872	kgs
d.	If Brunos storage vessel can hold only 2000 kgs of milk, what would be Brunos annual ordering and holding costs?		$1,103
e.	If Brunos storage vessel can hold only 7000 kgs of milk, what would be Brunos annual ordering and holding costs?		$1,197
f.	Brunos suppliers truck can carry 20,000 kgs of milk. The supplier does not want to deliver to more than 3 customers with each truck. Thus, the supplier requires a minimum order quantity of 6,500 kgs. If Bruno orders the minimum amount, what would be the sum of his annual ordering and holding costs? Assume he has a storage vessel large enough to hold 6,500 kgs.		$1,398
	(Round your answer to 3 decimal places.)
g.	Brunos supplier offers a 2.00% discount when a customer orders a full truck, which is 20,000 kgs. Assume Bruno can store that quantity and the product will not spoil. If Bruno orders a full truck, what would be the inventory holding and ordering cost incurred per kg of milk?		???
