44. You collect old model trains. One particular model increases in value at a rate of 6.5
percent per year. Today, the model is worth $1,670. How much additional money can you

45. Write a sentence explaining why present values decrease as the discount rate
increases.
Student answers will vary but should present the idea that when you can earn more
interest, you need less of your own money to reach the same future dollar amount.

46. Explain the relationship between compound interest and time.
Interest compounds exponentially over time. The longer the time period, the greater the
annual interest earnings.

47. Draw a graph illustrating the future value of $1, using five different interest rates
(including 0 percent) and maturities ranging from today to 10 years from now. Plot time to
maturity on the horizontal axis and dollars on the vertical axis. (Note: You do not need to
do any calculations. Just draw the graph using your intuition.)
Graphs should illustrate 3 concepts: 1) At zero percent interest, the $1 will not increase in
value. 2) The higher the interest rate, the higher the future value of $1. 3) The future
values should illustrate exponential growth.

48. You are considering two lottery payment streams, choice A pays $1,000 today and
choice B pays $1,500 at the end of five years. Using a discount rate of 5 percent, based on
present values, which would you choose? Using the same discount rate of 5 percent, based
on future values five years from now, which would you choose? What do your results
suggest as a general rule for approaching such problems? (Make your choices based purely
on the time value of money.)
PV of A = $1,000; PV of B = $1,175; FV of A = $1,276; FV of B = $1,500. Based on both
present values and future values, B is the better choice. The student should recognize that
finding present values and finding future values are simply reverse processes of one
another, and that choosing between two lump sums based on PV will always give the same
result as choosing between the same two lump sums based on FV.

49. At an interest rate of 10 percent and using the Rule of 72, how long will it take to
double the value of a lump sum invested today? How long will it take after that until the
account grows to four times the initial investment? Given the power of compounding,
shouldn't it take less time for the money to double the second time?
It will take 7.2 years to double the initial investment, then another 7.2 years to double it
again. That is, it takes 14.4 years for the value to reach four times the initial investment.
Compounding doesn't affect the amount of time it takes for an investment to double the
second time, but note that during the first 7.2 years, the interest earned is equal to 100
percent of the initial investment. During the second 7.2 years, the interest earned is equal
to 200 percent of the initial investment. That is the power of compounding.

50. Some financial advisors recommend you increase the amount of federal income taxes
withheld from your paycheck each month so that you will get a larger refund come April
15th. That is, you take home less today but get a bigger lump sum when you get your
refund. Based on your knowledge of the time value of money, what do you think of this
idea? Explain.
Some students may slip in a discussion about the benefits of forced savings, etc., but these
issues are based on preferences, not the time value of money. Based on the time value of
money, the student should recommend just the opposite. That is, withhold as little as
possible, while still avoiding tax penalties for under withholding, and pay the remaining
tax bill when it comes due the following year as next year's dollars are cheaper than this
year's dollars.
