You are being asked to evaluate the worthiness of an investment that requires you to spend $120,000 today in return for receiving $25,000 each year for seven years (starting one year from now). At the end of the seven year study period, the investment can be sold for $10,000. The MARR = 12% per year. Compute the AW of this investment. Round your answer to the nearest dollar. Answer should be -301

An area can be irrigated by pumping water from a nearby river. Two competing installations are being considered. The MARR is 12% per year and electric power for the pumps costs $0.06 per kWh. Recall that 1 horsepower (hp) equals 0.746 kilowatts. (11.2, 11.3) a. At what level of operation (hours per year) would you be indifferent between the two pumping systems? If the pumping system is expected to operate 2,000 hours per year, which system should be recommended? b. Perform a sensitivity analysis on the efficiency of Pump A. Over what range of pumping efficiency is Pump A preferred to Pump B? Assume 2,000 hours of operation per year, and draw a graph to illustrate your answer.
Combined-cycle power plants use two combustion turbines to produceelectricity. Heat from the first turbine’s exhaust is captured to heatwater and produce steam sent to a second steam turbine thatgenerates additional electricity. A 968-megawatt combined-cycle gasfired plant can be purchased for P450 million, has no salvage value,and produces a net cash flow (revenues less expenses) of P50 millionper year over its expected 30-year life.a. If the hurdle rate (MARR) is 14% per year, how profitable aninvestment is this power plant?b. What is the simple payback period for the plant? Is this investmentacceptable?

Now assume an investment cost of $1.50 per watt for the solar panels and the various equipment needs to connect the panels to the electricity grid. This investment cost is in year zero. Include the additional assumptions of: (i) the annual energy cost savings using $0.07 per KWH for electricity price with generated KWH computed in #a occur starting in year one with 1 to 1 net metering allowing the full benefit of energy cost savings to be obtained, (ii) a 20-year life span for the panels, (iii) zero annual maintenance costs, and (iv) an interest rate of 2.0% which reflects a post-tax certificate of deposit rate of interest. and having 29,226 as energy KWh generated per year calculate the following annual benefits and annual costs
