The price of a car you want is $42,000 today. Its
price is expected to increase by $1000 each year.
You now have $25,000 in an investment account,
which is earning 10% per year. How many years
will it be before you have enough to buy the car
without borrowing any money? Solve by (a) trial
and error, and (b) by spreadsheet.
Las Cruces' Virgin Galactic is considering two materials
for certain parts in a reusable space vehicle: carbon fiber
reinforced plastic (CFRP) and fiber reinforced ceramic
(FRC). The costs are shown below. Which should be
selected on the basis of a present worth comparison if
MARR = 10% per year? (a) Solve using tabulated factors.
(b) (Spreadsheet exercises) Solve using single-cell
functions. (c) Using your spreadsheet functions, will the
selection change if the estimated life of the CFRP
material is 4, rather than 2, years?

Since many U.S. Navy aircraft are at or near their usual retirement age of 30 years, military officials want a precise system to assess when aircraft should be taken out of service. A computational method developed at Carnegie Mellon maps in 3-D the microstructure of aircraft materials in their present state so that engineers can test them under different conditions of moisture, salt, dirt, etc. Military officials can then determine if an aircraft is fine, is in need of overhaul, or should be retired. If the 3-D system allows the Navy to use one airplane 2 years longer than it normally would have been used, thereby delaying the purchase of a $20 million aircraft for 2 years, what is the present worth of the assessment system at an interest rate of 8% per year?

- During recessionary periods, bonds that were issued many years ago have a higher coupon rate than currently issued bonds. Therefore, they may sell at a premium, a price higher than their face value, because of currently low coupon rates. A $50,000 bond that was issued 15 years ago is for sale for $60,000. What rate of return per year will a purchaser make if the bond coupon rate is 14% per year, payable annually, and the bond is due 5 years from now?
