How do I find the actual markup % if there are different costs and retail prices on the same purchase? (4000 total units: 1000 at $55 cost, 3000 at $50 cost with 1500 of them at $125 retail and retail the other half hasn't been determined). The planned markup % is 54.4%.

conditions . One of her best key resources has in stock 4 , 000 pairs of leather boots in this season's avant garde styling with balanced sizes and colors . Fifty percent of the resource's offering are the same styles as 500 pairs currently in stock , selling reasonably well at $200 retail . Providing she agrees to buy the complete group , the final landed cost negotiated is $50 per pair . Despite the fact that she considers this merchandise to be superb value at this sensational cost , she is hesitant about buying such a large quantity so late in the selling season . However , she receives a fax from her assistant informing her that the boots are moving quickly and sales have increased due to very cold , wintery weather conditions . She decides to buy this offering before a competitor has an opportunity to do so . Her strategy considerations are : . Retailing the group . . Shipping for present selling* . Integrating this purchase with present stock . . Obtaining the necessary markup percentage . She commits herself to the purchase , returns to her hotel and diligently works to map out the delivery and pricing factors . Her first decision is to start shipping some of these goods so they are* available , as soon as possible , for November selling . Therefore , despite the expense , she immediately sends 1 , 000 pairs by air because it is fast and it serves her purpose . This mode of transportation increases the delivered cost of the 1 , 000 pairs* form $50 to $55 a pair , and the retail is set at $150 . After making this decision , she turns her attention to the 500 pairs in stock currently selling at $200 a pair . Because mark down money is available , Miss Tee wants to begin to reduce the higher - priced boots while there is traffic . She can afford to reduce these 500 pairs from $200 to $150 , taking a larger than usual first mark down , because the markup of the 1 , 000 pairs ( that will sell simultaneously ) is so above average . On the balance of the 3 , 000 pairs , she divides half for December selling and retails them for $125 . The remaining* 1, 500 pairs she reserves for her annual Blizzard Promotion scheduled in January . For this event , her boot sales rely solely on merchandise that create " riots . " She did not yet set a retail price on the 2, 500 pairs for the January sale because she would like to price them at levels that are somewhat low , but will not* kill the required markup for the season . However , she calculated that a 54. 4% markup was needed on the entire purchase so that her seasonal markup target will be met
