Part A.
The total inventory cost for RMD will be as follows if they continue with their current policy of purchasing 600 cartons per month. Total Ordering cost = $200 x 12month = $2,400 Holding cost/Carton = 20% x $6 x 120 = $24 per annum per carton Holding cost p.m = $2 per carton Total Holding Cost =$2 x 600 cartons x 12 months = $14,400 Total inventory cost = $2,400 + $14,400 = $16,800
If the RMD used the Economic Order Quantity Model;
Total Inventory Cost = (Q/2)*Ch + (D/Q)*Co = (600/2) * $24 + (7,200/600) * $200 = $7,200 + $2400 = $9,600
