Joe Birra needs to purchase malt for his micro-brew production. His supplier charges $30 per delivery (no matter how much is delivered) and $1.3 per gallon. Joe's annual holding cost is 35% of the price per gallon, Joe uses 300 gallons of malt per week. a. Suppose Joe orders 750 gallons each time. What is his average inventory? 375 gallons (Round your answer to 2 decimal places.) b. Suppose Je orders 1500 gallons each time. How many orders does he place with his supplier each year? 10.40 orders How many gallons should Joe order from his supplier with each order to minimize the sum of ordering and holding costs? 1,434 gallons C.

What is the sum of ordering and holding costs per gallon? $ 838.500 per gallon (Round your answer to 2 decimal places.) Suppose Joe orders the quantity from part (c) that minimizes the sum of the ordering and holding costs each time he places an order with the supplier. What is the annual cost of the EOQ expressed as a percentage of the annual purchase cost? % e gallons If Joe's supplier only accepts orders that are an integer multiple of 1,000 gallons, f. how much should Joe order to minimize ordering and holding costs per gallon? Joe's supplier offers a 3.00% discount if Joe is willing to purchase 8000 gallons or g. more.
