Nowadays it is very important to reduce one's carbon "footprint" (how much carbon we produce in
our daily lifestyles). Minimizing the use of fossil fuels and instead resorting to renewable sources of
energy (e.g., solar energy) are vital to a "sustainable" lifestyle and a lower carbon footprint. Let's
consider solar panels that prewarm the water fed to a conventional home water heater. The solar
panels have an installed cost of $2,198, and they reduce the homeowner's energy bill by $28.5 per
month. The residual value of the solar panels is negligible at the end of their 8-year life. What is the
annual effective IRR of this investment?
The annual effective IRR of this investment is
%. (Round to two decimal places.)

they reduce the homeowner's energy bill by $426 per year. The residual value of the solar
panels is $550 at the end of their 9-year life. What is the annual IRR of this investment?
Use the trial-and-error method starting with an initial guess of 13%.
(a) The annual IRR of this investment is 10.72%. (Round to two decimal places.)
(b) If the homeowner's MARR is 10%, is the investment economical?
O A. No
B. Yes
The price of a car you want is $36,000 today. Its price is expected to increase by $1000 each year. You now have $22,000 in an
investment account, which is earning 8% per year. How many years will it be before you have enough to buy the car without borrowing
any money? (Use Goal Seek to determine the time taken.)
The time taken is determined to be
years.

- Suppose I have computed the cost of carbon per mile for my car at 0.011 per mile. Assume that the interest rate is 5% and that I drive the car 30,000 miles per year. What is present value of the carbon expense for five years? You will need to use the PV function in Excel or a financial calculator. In Excel the present value of a stream of monetary cash flows is given by -PV(rate, number of payments, payment amount) where rate is the interest rate. We enter the payment in Excel as a positive number. You can also compute the carbon cost per year and then discount those five values back to the present.arrow_forwardA doctor is on contract to a medium-sized oil company to provide medical services at remotely located, widely separated refineries. The doctor is considering the purchase of a private plane to reduce the total travel time between refineries. The doctor can buy a used Learjet 31A now for $1.700 million or wait for a new very light jet (VLJ) that will be available 3 years from now. The cost of the VLJ will be $2.600 million, payable when the plane is delivered in 3 years. The doctor has asked you, his friend, to determine the present worth of the VLJ so that he can decide to buy the used Learjet now or wait for the VLJ. The MARR is 14.00% per year, and the inflation rate is projected to be 3.200% per year. a) What is the present worth of the VLJ with inflation considered? b) Which plane should he buy?

The 700 MHz signals can travel long distances and more easily penetrate walls and other obstacles. The acquisition cost is $300 million. In addition, because networks that operate in the 700 MHz range are less expensive to build than those in other portions of the spectrum, Ducks estimates annual costs of $24 million over the next 9 years and no salvage value. During the same period, the company expects to generate annual revenue of $40 million by offering television and video to mobile-phone users. Calculate the net present worth of this investment if the company's minimum attractive rate of return (discount rate) is 13% per year.arrow_forward

- The Fischer-Tropsch (F-T) process was developed in Germany in 1923 to convert synthesis gas (i.e., a mixture of hydrogen and carbon monoxide) into liquid with some gaseous hydrocarbons. Interestingly, the F-T process was used in World War II to make gasoline and other fuels. The U.S. military can save one billion gallons per year of foreign oil by blending its jet fuel with F-T products. If the government expects inflation to average 3% per year, what is the equivalent uniform annual savings in fuel? The government's MARR is 7% per year, the study period is 40 years, and one gallon of jet fuel costs $2.80. The AW is $_______billion.arrow_forwardData for two 50-hr motors are follows: Honda Motor Kawasaki Motor Original Cost Annual Maintenance Life, years Efficiency Taxes and Insurance The cost of electricity per kilowatt-hour is two dollars.
