Esquire Company needs to acquire a molding machine to be used in its manufacturing process. Two types of machines that would be appropriate are presently on the market. The company has determined the following: Machine A could be purchased for $22,000. It will last 10 years with annual maintenance costs of $800 per year. After 10 years the machine can be sold for $2,310. Machine B could be purchased for $20,000. It also will last 10 years and will require maintenance costs of $3,200 in year three, $4,000 in year six, and $4,800 in year eight. After 10 years, the machine will have no salvage value. Required: Assume an interest rate of 8% properly reflects the time value of money in this situation and that maintenance costs are paid at the end of each year. Ignore income tax considerations. Calculate the present value of Machine A & Machine B. Which machine Esquire should purchase? Note: Negative amounts should be indicated by a minus sign. Do not round intermediate calculations.

Information for Terra Corp. Terra Corp is considering the purchase of a machine that is expected to cost $180,000.  The machine will require an additional $40,000 to have it shipped, modified, and installed.  The purchase of this machine is expected to require additional working capital of $20,000 upfront, which will be liquidated when the machine is sold off.  Terra expects to use the machine for 4 years, and then sell it for $95,000.  The machine will be fully depreciated over the four years, at a constant rate.  In each of the four years, Terra’s revenues are expected to be $85,000 higher than they would be without the machine.  Annual operating costs (not including depreciation) will also be higher, however, to the extent of $19,000.  The firm pays a 30% rate in taxes, and its cost of capital is 7.5%.  The initial outflow of cash for the proposed project is expected to be:     $220,000     $200,000     $180,000     $190,000     $240,000

One of two methods will produce solar panels for electric power generation. Method 1 will have an initial cost of $550,000, an annual operating cost of $160,000 per year, and a $125,000 salvage value after its three-year life. Method 2 will cost $830,000 with an annual operating cost of $120,000, and a $240,000 salvage value after its five-year life. The company has asked you to determine which method is economically better, but it wants the analysis done over a three-year planning period. The salvage value of Method 2 will be 35% higher after 3 years than it is after 5 years. If the company’s MARR is 10% per year, which method should the company select?

A small strip mining cola company is trying to decide whether it should purchase or lease a new clamshell. If purchased, the shell will cost $150,000 and is expected to have a $65,000 salvage value after 6 years. Alternatively, the company can lease a clamshell for $20,000 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 revenue of $12,000 per year. If the company’s MARR is 15% per year, should the clamshell be purchased or leased on the basis of future worth analysis.

In 2021, the Marion Company purchased land containing a mineral mine for $1,740,000. Additional costs of $676,000 were incurred to develop the mine. Geologists estimated that 400,000 tons of ore would be extracted. After the ore is removed, the land will have a resale value of $116,000. To aid in the extraction, Marion built various structures and small storage buildings on the site at a cost of $184,000. These structures have a useful life of 10 years. The structures cannot be moved after the ore has been removed and will be left at the site. In addition, new equipment costing $96,000 was purchased and installed at the site. Marion does not plan to move the equipment to another site, but estimates that it can be sold at auction for $4,000 after the mining project is completed. In 2021, 60,000 tons of ore were extracted and sold. In 2022, the estimate of total tons of ore in the mine was revised from 400,000 to 451,000. During 2022, 96,000 tons were extracted. Required: 1.

RealTurf is considering purchasing an automatic sprinkler system for its sod farm by borrowing the entire $30,000 purchase price. The loan would be repaid with four equal annual payments at an interest rate of 12%/year. It is anticipated that the sprinkler system would be used for 9 years and then sold for a salvage value of $2,000. Annual operating and maintenance expenses for the system over the 9-year life are estimated to be $9,000 per year. If the new system is purchased, cost savings of $15,000 per year will be realized over the present manual watering system. RealTurf uses a MARR of 15%/year for economic decision making. Based on a present worth analysis, is the purchase of the new sprinkler system economically attractive?
