A small strip-mining coal company is trying to decide whether it should purchase or lease a new clamshell. If purchased, the “shell” will cost $152,500 and is expected to have a $50,000 salvage value after 6 years. Alternatively, the company can lease a clamshell for only $16,000 per year, but the lease payment will have to be made at the beginning of each year. If the clamshell is purchased, it will be leased to other strip-mining companies whenever possible, an activity that is expected to yield revenues of $9,000 per year. If the company’s MARR is 13% per year, should the clamshell be purchased or leased on the basis of a future worth analysis? Assume the annual M&O cost is the same for both options.
The future worth when purchased is $
The future worth when leased is $

- The Tinkan Company produces one-pound cans for the Canadian salmon industry. Each year the salmon spawn during a 24-hour period and must be canned immediately. Tinkan has the following agreement with the salmon industry. The company can deliver as many cans as it chooses. Then the salmon are caught. For each can by which Tinkan falls short of the salmon industrys needs, the company pays the industry a 2 penalty. Cans cost Tinkan 1 to produce and are sold by Tinkan for 2 per can. If any cans are left over, they are returned to Tinkan and the company reimburses the industry 2 for each extra can. These extra cans are put in storage for next year. Each year a can is held in storage, a carrying cost equal to 20% of the cans production cost is incurred. It is well known that the number of salmon harvested during a year is strongly related to the number of salmon harvested the previous year. In fact, using past data, Tinkan estimates that the harvest size in year t, Ht (measured in the number of cans required), is related to the harvest size in the previous year, Ht1, by the equation Ht = Ht1et where et is normally distributed with mean 1.02 and standard deviation 0.10. Tinkan plans to use the following production strategy. For some value of x, it produces enough cans at the beginning of year t to bring its inventory up to x+Ht, where Ht is the predicted harvest size in year t. Then it delivers these cans to the salmon industry. For example, if it uses x = 100,000, the predicted harvest size is 500,000 cans, and 80,000 cans are already in inventory, then Tinkan produces and delivers 520,000 cans. Given that the harvest size for the previous year was 550,000 cans, use simulation to help Tinkan develop a production strategy that maximizes its expected profit over the next 20 years. Assume that the company begins year 1 with an initial inventory of 300,000 cans.arrow_forwardSeas Beginning sells clothing by mail order. An important question is when to strike a customer from the companys mailing list. At present, the company strikes a customer from its mailing list if a customer fails to order from six consecutive catalogs. The company wants to know whether striking a customer from its list after a customer fails to order from four consecutive catalogs results in a higher profit per customer. The following data are available: If a customer placed an order the last time she received a catalog, then there is a 20% chance she will order from the next catalog. If a customer last placed an order one catalog ago, there is a 16% chance she will order from the next catalog she receives. If a customer last placed an order two catalogs ago, there is a 12% chance she will order from the next catalog she receives. If a customer last placed an order three catalogs ago, there is an 8% chance she will order from the next catalog she receives. If a customer last placed an order four catalogs ago, there is a 4% chance she will order from the next catalog she receives. If a customer last placed an order five catalogs ago, there is a 2% chance she will order from the next catalog she receives. It costs 2 to send a catalog, and the average profit per order is 30. Assume a customer has just placed an order. To maximize expected profit per customer, would Seas Beginning make more money canceling such a customer after six nonorders or four nonorders?arrow_forwardI need 3 answersarrow_forward

First, he would like to be able to retire 20 years from now with retirement income of $15,000 per month for 20 years, with the first payment received 20 years and 1 month from now. Second, he would like to purchase a cabin in Rivendell in 10 years at an estimated cost of $100,000. Third, after he passes on at the end of the 20 years of withdrawals, he would like to leave an inheritance of $100,000 to Chani, his girlfriend. He can afford to save $3,000 per month for the next 10 years.

- Mansfield Energy Corp has recently taken over a fuel supply plant that is in close proximity to one of its competitors. The collection point for both fuel companies is located at the same seaport. The general manager of Mansfield Energy Corp intends to hire a consultant to train Mansfield Energy Corp’s employees regarding the new procedures for affixing the fuel lines at the collection point to the high-capacity storage tanks and is debating whether the competitor should be invited to attend given that they use the same seaport. The general manager is mindful of the high cost of hiring the consultant and sourcing the equipment to train Mansfield Energy Corp’s employees and is therefore hesitant to invite his competitors. The manager is also aware that there have been no accidents at the port since operations started 10 years ago and might not invite the competitors to participate in the training. The General Manager decides, based on the high price for the consultant (facilitation fee,…arrow_forwardA company plans to manufacture a product and sell it for $3.00 per unit. Equipment to manufacture the product will cost $250,000 and will have a net salvage value of $12,000 at the end of its estimated economic life of 15 years. The equipment can manufacture up to 2,000,000 units per year. Direct labour costs are $o.25 per unit, direct material costs are $0.85 per unit, variable administrative and selling expenses are $0.25 per unit, and fixed overhead costs are $200,000. What is the number of units that the company must manufacture in order to breakeven?arrow_forwardA car company is planning the introduction of a new electric car. There are two options for production. One is to produce the electric car at the company’s existing plant in Illinois, sharing production with its other products that are currently being produced there. If the sales of the electric car are moderate, this will work out well as there is significant capacity to produce all of the products there. However, if sales of the electric car are strong, this option would necessitate Adding a 3rd shift, which would lead to significantly higher costs. Another option is to build a new plant in Ohio. The new plant would have sufficient capacity to meet whatever level of demand for the new car. However, if sales of the new car not strong, the plant would be underutilized and less efficient. Since this is a new product, sales are hard to predict. The forecast indicates there is a 60% chance of strong sales (annual sales of 100,000), and 40% chance of moderate sales (annual sales of…arrow_forward
