Engineering Economics 6th edition, Mountain Pass Canning Company has determined that any one of four machines can be used in one phase of its canning operation. The costs of the machines are estimated below, and all machines have a 10-year life. If theMARR is 12% per year, determine the one machine that should be selected on the basis of the rate of return analysis (using the PWROR equation). Machine 1: -15,000; +1,000; +4,000; Machine 2: -25,000; -500; +6,000; Machine 3: -18,000; +2,000; +5,000; Macine4: -35,000; -700; +8,000. (For each machine the numbers represent, in order: First Cost, ;SalvageValue,; Annual income

Given his plot of land, a farmer uses labor (10 workers), capital (5 pieces of equipment), and fertilizer (5 tons) to produce corn. He has figured that each additional worker hired over the course of the growing season adds 5000 bushels to his cro..
A mining company plans to invest $50,000 in a project. The annual operating cost is expected to be $6,000, and the annual income is expected to be $22,000. THe salvage value will be $5,000 at the end of 5 year life.
A $40,000 investment you made yields annual payments of $22,000, $14,000, $17,000, $25,000, and $38,000 at the end of the next 5 years respectively. Calculate the rate of return represented by this cash flow to three significant figures.
You own a building that has 4 possible uses: a cafe, a craft store, a hardware store, and a bookstore. The value of the building in each use is $2000; $3000; $4000; and $5000, respectively. You decide to open a hardware store. The opportunity cost..
The company interest rate (MARR) is 15%. The company will make a down payment of 25% of the first cost for the Pick-M-Up and 15% of the first cost for Carter's. The loan will have an annual effective interest rate of 10% with annual payments.
Suppose you are a monopolist able to produce your chosen output at a constant average (and thus marginal) cost of ATC = MC = $5. You face a market demand curve given by Q = 53 - P or inverse demand given by P = 53 - Q, where Q is the output provid..
Illustrate that the previous manager, who was charging the monopoly price per beer, was not maximizing profits as accused by the owner. That is, find an alternate pricing scheme that results in more profits per customer than the monopoly scenario.
What are the marginal abatement cost functions for each of the two areas? Calculate the loss in the two areas due to over-control (for the rural area) and under-control (for the urban area).
Suppose that the Fed's inflation target is 2%, potential output growth is 3.5%, and velocity is a function of how much the interest rate differs from 5%: %^V= 0.5 X (i-5). Suppose that a model of the economy suggests that the real interest rate is..
a city is spending $20 million on a new sewage system. The expected life of the system is 40 years, and it will have no market value at the end of its life. Operating and maintenance expenses for the system are projected to average $0.6 million pe..
Calculate output per worker and consumption per worker for each country. Which country has the highest output per worker? The highest consumption per worker?
