Could someone write the correct answers for the ones I have incorrect

The A&M Hobby Shop carries a line of radio-controlled model racing cars. Demand for the cars is assumed to be constant at a rate of 50 cars per month. The cars cost $70 each, and ordering costs are approximately 515 per order, regardless of the order size. The annual holding cost rate is 20% (a) Determine the economic order quantity and total annual cost (in ) under the assumption that no backorders are permitted. (Round your answers to two decimal places.) Q* = 35.88 TC = $ 502.00 (b) Using a 545 per-unit per-year backorder cost, determine the minimum cost inventory policy and total annual cost (in $) for the model racing cars. (Round your answers to two decimal places.) Q* = 41.08 TC = $ 240.57 x (c) What is the maximum number of days a customer would have to wait for a backorder under the policy in part (b)? Assume that the Hobby Shop is open for business 300 days per year. (Round your answer to two decimal places.) 5.16 x days (d) Would you recommend a no-backorder or a backorder inventory policy for this product? Explain. Yes, the maximum wait is less than a week and the backorder case has a lower cost than the EOQ case. Yes, the maximum wait is over a week long, but the cost savings of the backorder case is large enough to justify a long wait. O No, the maximum wait is over a week long and the EOQ case has a lower cost than the backorder case. O No, the maximum wait is over a week long, which does not justify the cost savings of the backorder case. O No, the maximum wait is less than a week but the EOQ case has a lower cost than the backorder case. (e) If the lead time is six days, what is the reorder point for both the no-backorder and backorder inventory policies? (Round your answers to two decimal places.) EOQ r = 12 Backorder r = 6.84 X
