Engineering economy: The fixed costs incurred by the engineering department are $280,000 per year. Variable costs are 20% of the annual revenue. If annual revenue is $560,000, determine the annual profit or loss.
An industrial plant has hired a contractor to develop a solar farm nearby for the industrial plant's electricity consumption. During the 3-year construction period, the contractor will need to run a generator to power the construction. Cost analysis from previous projects indicates: Generator Brand Installed Cost Cost per Hour A $22M $500 B $23M $400 C $25M $250 D $30M $150 At the end of 3 years, the generator will have a salvage value equal to the cost of removing them. The generator will operate 6,000 hours per year. The lowest interest rate at which the contractor is willing to invest money is 7%. (The minimum required interest rate for invested money is called the minimum attractive rate of return, or MARR.) Select the alternative with the least present worth of cost. O Choice "C" with $29,872,900 O Choice "B" with $29,298,320 O Choice C with $28,936,450 O Choice "A" with $29,872,900
