4 David Polston prints up T-shirts to be sold at local concerts. The T-shirts sell for $18.90 each but cost David only $4.60each. However, because the T-shirts have concert-specific information on them, David can sell a leftover shirt for only$4.50. Suppose the demand for shirts can be approximated with a normal distribution and the mean demand is 170shirts, with a standard deviation of 30.Click the icon to view the normal probability table for z ≥ 0.Click the icon to view the normal probability table for z ≤ 0.What is the target service level?David's target service level is %. (Enter your response as a percentage rounded to two decimal places.)

13 Pam’s demand for hats is normally distributed with mean 500 and standard deviation 100. She sells her hats for $50 each and buys hats for $10 each, and anything she can't sell by the end of the year, the wholesaler will buy for $5 each. How many hats should she order for next year to maximize profit?
Please answer questions 9 and 10 based on this data. Daily demand for packages of five videotapes at a warehouse store is found to be normally distributed with a mean of 50 and a standard deviation of 5. When the store orders more tapes, the orders take four days to arrive. Assume the store is open 360 days a year. If the store wants the probability of stocking out to be no more than 5%, and demand each day is independent of the day before, what should be the safety stock? Please round your answer to two decimals. Safety stock= 17 Question 10 4 pts If the store wants the probability of stocking out to be no more than 5%, and demand each day is independent of the day before, what reorder point should be set?

Dan's Independent Book Store is trying to decide how many copies of a book to purchase at the start of the upcoming selling season. The book retails at $28.00. The publisher sells the book to Dan at $20.00. Dan will dispose of all of the unsold copies of the book at 50% off the retail price, at the end of the season. Dan estimates that demand for this book during the season is normal with a mean of 1000 and a standard deviation of 250. The publisher is thinking of offering the following scheme to Dan. At the end of the season, they will buy back unsold copies at a pre-determined price of $17.00. However, Dan would have to bear the costs of shipping unsold copies back to the publisher at $1.00 per copy. What is the quantity that Dan should order, to maximize his expected profits?
A restaurant uses 100 per week or 5,000 quart bottles of ketchup each year. The ketchup costs $3.00 per bottle and is served only in whole bottles because its taste quickly deteriorates. The restaurant figures that it costs $10.00 each time an order is placed, and holding costs are 20 percent of the purchase price. It takes 3 weeks for an order to arrive. The restaurant operates 50 weeks per year. The restaurant would like to use an inventory system that minimizes inventory cost. The restaurant has figured that the most economical order size or EOQ is approx. 409 (rounding up the decimals). Approximately, what is the time between two orders (in terms of weeks) 08 06 04 02 None of the above

You run a food bar in UCLA Ackerman, and you sell chocolate croissants for breakfast. Your daily demand for chocolate croissants is on average 50, with a standard deviation of 8. The unit cost of a croissant is $0.70, and you sell at a unit price of $3.00. The refrigerated chocolate croissant must be consumed within 7days (one week) after purchased from your supplier, so you dispose leftover inventory and purchase fresh croissants once every week. Assume the demand in each of the seven days is independently distributed. (The z-table for normal distribution is attached.) (a) What is the optimal weekly purchase quantity for the chocolate croissant? What is average inventory? A student leader, Mark, came to you one day and told you that Anderson School would hold a special event next Thursday morning, and there would be additional demand for the chocolate croissant on that day. Mark wants to reserve a certain amount of croissant from you and sell in the special event at the regular price.…
A grocer carries 9,300 different items in their store. In a normal week, demand occurs for 4,900 of these items. Of those 4,900 items, 175 are not available for the entire week and another 330 items are available for only part of the week. Round your answer as a percentage rounded to one decimal place. What is the grocer's in-stock probability during a normal week? %
Annual demand is 16000 units, cost per order is $75 and carrying cost per unit as a percentage is 10%. The company works 250 weeks a year; the lead-time on all orders placed is 6 working days. Assuming constant lead-time demand, and a unit cost of $45 what is the economic order quantity? What is the reorder point. If lead-time demand shows variability that follows a normal distribution with a mean μ =420 and a standard deviation σ =20, what will the revised reorder point if two stock-outs (shortages) are allowed? What is the company’s reorder point if the probability of a stock-out on any cycle is restricted to 0.05?
A fish restaurant sells fish for 50$ per kg and buys it from the suppliers for 10$ per kg. Fish that were not sold during the day go bad. A manager has estimated that daily demand for fish is normally distributed with a mean of 20kg and a standard deviation of 5 kg. The manager has to decide how much fish to order per day. Find a profit-maximizing order.
XYZ Company must order tires from its warehouse. It costs $10400 to place an order and to review the inventory level. Annual tire sales are normally distributed with mean 18000 and variance 4,000,000. It costs $8 per year to hold a tire in inventory, and each order arrives two weeks after being placed. The Company uses periodic review (R, S) policy. What is the review interval R (in years), estimated using EOQ.? Select one: a. 0.3801 b. 0.19 c. 0.2687 d. 1.075 e. 0.1267
Consider two products A and B that have identical cost, retail price and demand parameters and the same short selling season. The newsvendor model is used to manage inventory for both products. Product A is to be discontinued at the end of the season this year, and the leftovers will be salvaged at 65% of the cost. Product B will be re-offered next summer, so any leftovers this year can be carried over to the next year while incurring a holding cost on each leftover unit equal to 20% of the product's cost. How do the stocking quantities for these products compare? Multiple Choice Stocking quantity of product A is higher. Stocking quantity of product B is higher. The answer cannot be determined from the data provided. Stocking quantities are equal.
