Dorothy lacks cash to pay for a $840.00 dishwasher. She could buy it from the store on credit by making 12 monthly payments of $71.52. The total cost would then be $858.24. Instead, Dorothy decides to deposit $70.00 a month in the bank until she has saved enough money to pay cash for the dishwasher. One year later, she has saved $882.00—$840.00 in deposits plus interest. When she goes back to the store, she finds the dishwasher now costs $886.20. Its price has gone up 5.50 percent.
Was postponing her purchase a good trade-off for Dorothy?
COMPUTING REORDER POINTS (ROP) FOR IPHONES WITH AND WITHOUT SAFETY STOCKAn Apple store has a demand (D) for 8,000 iPhones per year. The firm operates a 250-day working year.On average, delivery of an order takes 3 working days, but has been known to take as long as 4 days. Thestore wants to calculate the reorder point without a safety stock and then with a one-day safety stock.APPROACH c First compute the daily demand and then apply Equation (12-6) for the ROP.Then compute the ROP with safety stock.
In a standard Cournot environment:
All firms choose a price they will sell their products at simultaneously
Firms choose whether they play quantities simultaneously as actions or prices
All firms choose a quantity they supply simultaneously
O Some firms choose quantity and some firms choose a price

Each apartment building contains 120 rental units, but the owner is having cash flow problems due to an average vacancy rate of nearly 50 percent. The apartments in each building have comparable floor plans, but some buildings are closer to campus than others. Jasmine’s accumulated data from last year on the number of apartments rented, the rental price (in dollars), and the amount spent on advertising (in hundreds of dollars) at each of the 12 apartments are available below. These data, along with the distance (in miles) from each apartment building to campus, are presented below.

Thank you so much.arrow_forwardGlobal Logistics needs to rent space for storing product for the next three years. The following information regarding the demand and spot price is available. Current demand for the product is 150,000. Historically, Global Logistics has required 1500 square feet to store 1500 units of the product. Demand for the product can go up by 20% with a probability of 0.7 or down by 20% with a probability of 0.3. Global Logistics can sign a three-year fixed lease to rent 150,000 square feet of space at $1.00 per square foot per year. The firm may also choose to obtain warehousing space on the spot market. The current spot market price is $1.20 per square foot per year. The spot price can go up by 10% with a probability of 0.8 and can decrease by 10% with a probability of 0.2.

- Barbara Flynn sells papers at a newspaper stand for $0.40. The papers cost her $0.30, giving her a $0.10 profit on each one she sells. From past experience Barbara knows that: a) 20% of the time she sells 150 papers. b) 20% of the time she sells 200 papers. c) 30% of the time she sells 250 papers. d) 30% of the time she sells 300 papers. Assuming that Barbara believes the cost of a lost sale to be $0.05 and any unsold papers cost her $0.30 and she orders 250 papers. Use the following random numbers: 14, 4, 13, 9, and 25 for simulating Barbara's profit. (Note: Assume the random number interval begins at 01 and ends at 00.) Based on the given probability distribution and the order size, for the given random number Barbara's sales and profit are (enter your responses for sales as integers and round all profit responses to two decimal places): Random Number Sales Profit 14 4 13 9 25arrow_forwardThe Hawkins Supply Company is currently faced with an inventory rotation problem. This difficulty stems from the fact that some supplies must be used prior to a stated expiration date. Upon receipt, a new shipment of these perishable items must be stacked beneath the boxes that are currently in inventory. A substantial amount of time is consumed in restacking the items according to their expiration dates.The company would like to reduce the double and sometimes triple handling of items. How can this goal be achieved? Are there alternative solutions which might also be effective?arrow_forwardIn the fashion retail industry transshipment is the flow of the products from a retail location to another one to satisfy the demand at the receiver location. Sender only sends a product if it has excess inventory to its demand and it occurs to rebalance the inventory among retail locations. Assume that there is a retailer with I stores. There are O products nominated for transshipment. The available inventory rio, i = 1,2, ..., I, o = 1,2, ..., 0, and demand levels dio, i = 1,2, ..., I, o = 1,2, ..., 0, for all O, stores are known. Moreover, the sales prices of these products are known and are the same in all stores, po, o = 1,2, ... 0. There is a transportation cost when a product is sent from a store to another, Cij, i, j = = 1, 2, ... D which is independent for the type of the product. Assume that if a product o is transshipped from store i, all its available inventory, i.e., rio, must be sent to a single store, thus, partial transshipment is not allowed.
