Warren, the owner of home audio system chain stores AU, has been working with a supplier TLC, and has purchased stereo systems for $100/unit. Warren has used EOQ model when placing an order. His assumption was as shown below: Monthly demand 250 units Ordering cost $90 per order Holding cost 12% per unit cost What is the economic order quantity? (If necessary, round to the nearest integer.) 61 units. Warren recently receive a letter from TLC that showed the unit price of the stereo system would be $130 because of the inflation and the shortage of semiconductors. Warren decided to negotiate with TLC. Eventually, the sales rep of TLC has made the following offer to Warren: If Warren orders more than 250 units at a time, the cost per unit is $115.00. Question 7 Not yet answered Points out of 8.00 P Flag question Warren recently receive a letter from TLC that showed the unit price of the stereo system would be $130 because of the inflation and the shortage of semiconductors. Warren decided to negotiate with TLC. Eventually, the sales rep of TLC has made the following offer to Warren: If Warren orders more than 250 units at a time, the cost per unit is $115.00. If the order is between 150 and 249 units at a time, the cost per unit is $130.00. However If the order is from 1 to 149 units at a time, the cost per unit is $150.00. Warren revised his assumptions and estimates monthly demand will be declined to be 225 units of stereo systems. Holding cost will increase to 15 percent of unit price. The cost to place an order will be higher to be $120.00. The information is summarized as below: (This is from 'Inventory' tab of the final exam worksheet.) Quantity purchased Unit price 1-149 units $150 150-249 units $130 250 or more units $115 Monthly demand 225 units Ordering cost $120 per order Holding cost 15% per unit cost Warren is interested in the most cost-effective ordering policy. What is the optimal (most cost-effective) order quantity if Warren uses the quantity discount model? (If necessary, round to the nearest integer) Question 8 Not yet answered Points out of 6.00 P Flag question.

What is the optimal (most cost-effective) annual total cost under the quantity discount model? (If necessary, round to the nearest dollar, such as 134500.)
