Chapter 6, Problem 9P
DuPont claims that its synthetic composites will replace metals in the construction of future automobiles. “The fuel mileage will double,” says DuPont. Suppose the lighter and stronger “composite automobile” will get 50 miles per gallon of gasoline, and that gasoline costs $3.50 per gallon. The anticipated life of the automobile is six years, i = 10% 10% per year, and annual travel is 20,000 miles. The conventional car averages 25 miles per gallon. (6.4)
- a. How much more expensive can the sticker price of the composite automobile be and still have it as an economical investment for a prospective auto buyer? State all important assumptions.
- b. What is the trade-off being made in Part (a)?

A new six-speed automatic transmission for automobiles offers an estimated 4% improvement in fuel economy
compared to traditional four speed transmissions in front-wheel drive cars. If a four-speed transmission car averages
28 miles per gallon and gasoline costs $4.00 per gallon, how much extra can a motorist pay for a fuel-efficient six-
speed transmission? Assume that the car will be driven for 130,000 miles over its lifetime of 15 years. The motorist
can earn 7% per year on investments. Assume miles driven each year are roughly constant.

Your company grant you a P 100,000 loan for personal purposes. The annual payment is P 8,880 and the APR (Annuel %age rate) is 8% for 30 years. Your company decides that it can afford to pay P10,000 per year. After how many payments (in years) will the loan be paid off. (choose the nearest value)
It is likely that your college tuition will increase an average of 8% per year for the next 4 years. The annual cost of tuition at the beginning of your freshman year in college will be $12,000 (A1). How much money will you and your parents have to deposit in a mutual fund account one year prior to your freshman year to pay for your tuition for the 4 years you will spend earning your degree in engineering? The mutual fund will earn an average of 5% annual interest.

- An engineer will deposit 15% of her salary each year into a retirement fund. If her current annual salary is $80000 and she expects that it will increase by 5% (g) each year, what will be the present worth of the fund after 35 years if it earns 5% interest? (Answer: $400,000)arrow_forwardAn 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_forwardSuppose a friend of yours invests $100 each month in an individual retirement account (IRA) for a decade and earns an unbelievable APR of 12% a year (1% per month) on her investment. She will end up with $100 (F/A, 1%, 120) = $100 (230.0387) = $23,003.87 after 10 years. If you decide to invest $200 each month over 10 years, but can earn only a meager APR of 3% per year on it, roughly how much will you have accumulated after 10 years?Choose the closest answer.

You then deposit $3,300 each year for five more years (starting at the end of Year 6). At the end of Year 15, you withdraw the entire amount. There are no additional payments in Years 11 through 15. The account earns 8% per year.

Replacing half the ferrous metals in current automobiles could reduce a vehicle’s weight by 60% and fuel consumption by 30%. One impediment to using carbon fibers in cars is cost. If the justification for the extra sticker price of carbon-fiber cars is solely based on fuel savings, how much extra sticker price can be justified over a six-year life span if the carbon-fiber car would average 39 miles per gallon of gasoline compared to a conventional car averaging 30 miles per gallon? Assume that gasoline costs $4.00 per gallon, the interest rate is 20% per year, and 117,000 miles are driven uniformly over six years.arrow_forwardLiam O’Kelly is 20 years old and is thinking about buying a term life insurance policy with his wife as the beneficiary. The quoted annual premium for Liam is $8.48 per thousand dollars of insurance coverage. Because Liam wants a $100,000 policy (which is 2.5 times his annual salary), the annual premium would be $848, with the first payment due immediately (i.e., at age 21). A friend of Liam’s suggests that the $848 annual premium should be deposited in a good mutual fund rather than in the insurance policy. “If the mutual fund earns 10% per year, you can become a millionaire by the time you retire at age 65,” the friend advises. Solve, a. Is the friend’s statement really true? b. Discuss the trade-off that Liam is making if he decides to invest his money in a mutual fund.arrow_forward
