Please use a financial calculator to solve. Be sure to list your steps. You are evaluating two different silicon wafer milling machines. The Techron I costs $237,000, has a three-year life, and has pretax operating costs of $62, 000 per year. The Techron II costs $ 415,000, has a five - year life, and has pretax operating costs of $ 35,000 per year. For both milling machines, use straight - line depreciation to zero over the project's life and assume a salvage value of $39, 000. If your tax rate is 21 percent and your discount rate is 8 percent, compute the EAC for both machines. (Your answer should be a negative value and indicated by a minus sign. Do not round intermediate calculations and round your answers to 2 decimal places, e.g., 32.16.)
You are considering buying a 10-year-old machine for $280, or a new fuel-efficient machine for$600. The new machine will save you $5 per month on your fuel bill, and you will be able to sellit for $300 in 10 years. The used machine will have no resale value at that time. Assume theinterest rate is 3% per year. According to the information given, which machine will you buy?
You invested $100,000 in a project and received $40,000 at n = 1, $40,000 atn = 2, and $30,000 at n = 3 years. You need to terminate the project at the end of year 3. Your interest rate is 10%; what is the project balance at the time of termination?(a) Gain of $10,000(b) Loss of $8,039(c) Loss of $10,700(d) Just break even
3. The annual worth method An office supply company has purchased a light duty delivery truck for $15,000. It is anticipated that the purchase of the truck will increase the company’s revenue by $10,000 annually, whereas the associated operating expenses are expected to be $3,000 per year. The truck’s market value is expected to decrease by $2,500 each year it is in service. If the company plans to keep the truck for only 2 years, what is the annual worth of this investment? The MARR = 18% per year

Mr. Don is the director of A-Design Inc., a federally incorporatedcompany in Canada, specializing in the design and manufacturing of armrests for the wheelchair industry. A-Design invested $100,000 in a production machine, which has a useful life of 10 years, and put $10,000 in its bank account. In an attempt to improve company sales and profits, Mr. Don planned tooffer two purchasing options to the clients of his company. Option 1:$250 deposit upfront$500 yearly fee for 5 years Option 2:$1300 deposit upfront$300 yearly fee for 3 years Calculate the depreciated cost per year of the machine.
When buying a luxury truck, three documents are signed, each one for $150,000.00, with expiration in one, two and three months. Instead, it is proposed to make two equal payments, the first in one month and the second in two months. Calculate the amount of each of the payments if the automaker collects a nominal 12.5% capitalized monthly.
Hajia Timber Ltd (GTL) produces and exports lumber and planks. It owns a plant whichhas value of GHC 1,800,000 as at 1 January 2010. The government of Ghana,passes alegislation that restricts the exportation of lumber. Consequently GTL has to reduceproduction by 40%. Cash flow forecast for the next five years included in the budgetsubmitted for management approval in January 2010 shows the following:Year Cash flows (GHC)2010 552,0002011 506,0002012 376,0002013 250,0002014 560,000The cashflow forecast for 2014 includes expected proceeds from disposal of the plant. Thecash flow projections also ignore the effects general upwards movement in prices.It is estimated that if the plant is sold in January 2010, it would realize the net proceeds ofGHC 1,320,000. The costs of capital for GBL is 15% (ignoring inflationary effect)RequiredCalculate the recoverable amount of the plant and impairment loss (if any).
is considering a new 3- year - long project that would involve using specialized scanning software to scansubmitted screenshots in low resolution and convert them into high resolution text documents that there's currently astrong market for. Course Hero requires a 17 percent annual return on this uncertain project, high enough tocompensate for the underlying uncertainty of future cash inflows. A decision to accept the project would be followed byan immediate investment of $5.8 million into purchasing the software. At the end of the project Course Hero is hoping tobe able to find a different company in similar line of business that would be willing to pay $449, 400 for the software andits future ownership.other similar software, its value will be dropping over its economic life according to the 3- yearMACRS depreciation schedule. (See this MACRS Table) Course Hero pays taxes on its annual income and other taxablecash flows according to a 32 % tax rate. Course Hero estimates $5, 136, 000…
