An environmentally friendly 3,100-square-foot green home (99% air tight) costs about 8%
more to construct than a same-sized conventional home. Most green homes can save 14%
per year on energy expenses to heat and cool the living space. For a $261,000 conventional
home with a heating and cooling bill of $3,000 per year, how much would have to be saved
in energy expenses per year to justify this home (i.e., B-C ratio greater than or equal
to one)? The discount rate is 11% per year, and the expected life of the home is 23 years.

would have to be saved in energy expenses per year to justify this home. (Round to the
nearest dollar.)
Should Jim sell his Minivan?
Jim's 1998 minivan is quite functional, but it only
averages 20 miles per gallon (mpg). He has found
a somewhat newer vehicle (roughly the same
functionality) that averages 26 mpg. He can sell
his current minivan for $2800 and purchase the
newer vehicle for $4,000. Assume a cost of
gasoline $4.00 per gallon.
How many miles per year must Jim drive if he
wants to recover his investment in three years?
Assume an interest rate of 6%, zero salvage value
for either vehicle after three years, and identical
maintenance cost.
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.

- 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_forwardPlease as soon as possible.thank youarrow_forwardA new automotive “dry paint” separation process is environmentally friendly and is expected to save $8.00 per car painted at a Detroit plant.

- Please do fastarrow_forwardShin likes to spend a (relatively small) portion of his income on vacations to Cabo San Lucas (a popular resort area in Mexico). On these trips, he either stays at a four-star resort with panoramic ocean views or a more modest, and slightly deteriorating hotel in the noisy part of town. Understandably, the four-star hotel is significantly more expensive. Suppose that the four-star hotel costs $5000/trip while the hotel costs just $500/trip. In recent years, the price of airfare has risen significantly, a change that affects the cost of his trips the same regardless of where he stays. Suppose that airfare has increased from $300/trip to $1000/trip. Why is it that following the higher travel prices, Shin is likely to spend more of his vacations at the four-star resort when he travels? (Assume that the hotel rates and Shin's preferences are fixed).arrow_forwardA construction manager just starting in private practice needs a van to carry crew and equipment. She can lease a used van for $3910 per year, paid at the beginning of each year, in which case maintenance is provied. Alternatively, she can buy a used van for $5407 and pay for maintenance herself. She expects to keep the van for three years at which time she could sell it for $1045. What is the most she should pay for uniform annual maintenance to make it worthwhile to buy the van instead of leasing it, if her MARR is 20%? Enter your answer as follow: 123456arrow_forward

The generating set costs P 70,000 with a life of 10 years with a salvage value of P 10,000. The daily operating cost is P 50 per hour. During a brownout, the office operation will be delayed which cause a loss of P 150 per hour.
