An indium-gallium-arsenide-nitrogen alloy developed at Sandia National Laboratory is said to have potential uses in electricity-generating solar cells. The new material is expected to have a longer life, and it is believed to have a 40% efficiency rate, which is nearly twice that of standard silicon solar cells. The useful life of a telecommunications satellite could be extended from 10 to 15 years by using the new solar cells. What rate of return could be realized if an extra investment now of $900,000 would result in extra revenues of $450,000 in year 11, $500,000 in year 12, and amounts increasing by $50,000 per year through year 15?

An integrated, combined cycle power plant produces 285 MW of electricity by gasifying coal. The capital investment for the plant is $570 million, spread evenly over two years. The operating life of the plant is expected to be 20 years. Additionally, the plant will operate at full capacity 75% of the time (downtime is 25% of any given year). The MARR is 6% per year

- A 2,000 square foot house in New Jersey costs $1,725 each winter to heat with its existing oil-burning furnace and expected to increase $25 each year. For an investment of $3,000, a natural gas furnace can be installed, and the winter heating bill is estimated to be $1,000 and expected to increase $15 each year. If the homeowner's MARR is 7% per year, what is the discounted payback period of this proposed investment?

ABC Insulation, Inc., told the owner of the plant that the heat loss can be reduced by 80% if he is willing to spend $401,000 to install its innovative insulation material. The cost of heat loss is expected to rise by $2100 per year (uniform gradient) after the next year. The owner plans to keep the present building for 15 more years. Assume MARR (minimum acceptable rate of return) is 4% per year. (a) What is the present equivalent value of the cost savings in the reduction of heat loss for these 15 years?

- An environmentally friendly green home (99% air tight) costs about 8% more to construct than a conventional home. Most green homes can save 15% per year on energy expenses to heat and cool the dwelling. For a $250,000 conventional home, how much would have to be saved in energy expenses per year when the life of the home is 30 years and the interest rate is 10% per year? Assume the additional cost of a green home has no value at the end of 30 years.arrow_forwardConstructing a new road at a cost of $ 670,000 will result in a saving of travel time for users diverted to it. However , because the road is expected to deteriorate over time, travel time savings decline by $50,000 each year from $250,000 in the first year to $50,000 in year 5. What is the Rate of Return on the investmentarrow_forwardA certain medical device will result in an estimated $15,000 reduction in hospital labor expenses during its first year of operation. Labor expenses (and thus savings) are projected to increase at a rate of 7% per year after the first year. Additional operating expenses for the device (maintenance, electric power, etc.) are $3,500 annually, and they increase by $250 per year thereafter (i.e., $3,750 in year two and so on). It is anticipated that the device will last for 10 years and will have no market value at that time. If the MARR is 10% per year, how much can the hospital afford to pay for this device?
