12. A recapping plant is planning to acquire a new diesel engine set to replace its present unit which they run during power interruptions. The new diesel set would cost $135,000 with a five years life and zero residual value. Annual operating cost would be $150,000. On the other hand, the present generating set has a remaining life of 5 years. Its present value is $7,500 but has a zero residual value after 5 years. Annual operating costs is placed at $187,500. If MARR=D10%, which is more profitable - to buy the new generator set or retain the present set? Calculate the difference in annual costs between the two alternatives.

Answer FAST.... it's urgent A new office building has been constructed at a cost of $3,000,000. It is estimated to have a life of 50 years with a value at that time of $200,000. It will have maintenance costs of $10,000 per year. It will also have major repairs costing $80,000 that occur at years 10, 20, 30 and 40. It will have additional repairs at the end of year 25 costing $250,000. Determine the equivalent uniform annual cost if the rate of interest of the firm is 7%

6. A certain building has an old heating system. Annual cost of heating the building is currently $26,000 on average. An energy consultant estimates that the heating bill can be reduced to $10,000 a year if $49,000 is invested to convert the old heating system to a new one. If the new heating system is adopted, there will be an extra maintenance fee of $2,000 each year. Both the old and new systems will have a zero salvage value at the end of their service lives and again both of them are expected to serve for a maximum of 20 years starting from now. What is the net annual equivalent worth for this investment in the new heating system, assuming a MARR of 11%? The annual net worth of installing the new heating system is $ (Round to the nearest dollar.)

3. The chimney of the Chemical Enginering building was built 25 years ago in today's currency for 5,000,000 TL. The economic life of this chimney is estimated to be 50 years and there is no salvage value. This damaged chimney must be strengthened or demolished and rebuilt. 3,000,000 TL is required for the strengthening of the chimney and the economic life will increase 30 years as a result of the strengthening. In this case, the annual maintenance cost of the chimney is estimated to be 250,000 TL. If the chimney is rebuilt, 7,500,000 TL will be spent and its economic life will be 60 years. In this case, it is estimated that the annual maintenance cost of the chimney will be 100,000 TL and there will be no salvage value. It is estimated that the demolishment expenses of the old chimney will be 500,000 TL. If interest rate is 20%, as a Chemical Engineer, what kind of decision would you recommend the university to take regarding the chimney of the building?
What is the total lifetime cost of the system given the following information? The initial cost of the system is $4800. The system has annual maintenance costs of $175. On the fourth year, an overhaul cost of $350 is scheduled. The system is expected to last for 5 years. The discount rate is 8%. Answer to the nearest dollar $________.00.

XYZ Inc is looking at a project to manufacture widgets. Assume we have the following data: • The initial cost of the project is $1,080,000. • The project is expected to last 7 years, at which time the project will be abandon. • Assume each widget will cost $8.00 each to produce and the selling price will be $12.00. Production fixed costs are expected to be $248,400 annually. • The company has computed that the PVCCATS associated with this project will be $237,600. Also, the company uses a discount rate of 9% for capital projects and XYZ pays tax at a rate of 10%. XYZ is unsure as to how many widgets they will sell annually. The marketing department has provided that the expected number of units sold annually, N is E(N) = 128,000 units with a standard deviation of o= = 21,000 units.
