6. The operating cost (from consumption of electricity) of a refrigeration
storage unit was $14,000 last year. Since the unit operates continuously, its
power consumption is expected to remain the same in the future. If the cost
of electrical power is predicted to increase at the rate of 8% annually, find
the actual-dollar cash flow representing the operating costs of this unit over
the next 5 years.

7. An annuity ( ‫ )مبالغ ناية‬provides for 10 consecutive end-of-year payments
of $10,000, beginning one year from the present. The inflation rate for the
next 10 years is estimated to be 12% compounded annually. If the inflationfree rate is 7% compounded annually, what is this annuity worth in terms of
a single equivalent amount of present-day dollars? Calculate using:
a. Actual-dollar analysis.
b. Constant-dollar analysis.

8. The purchase of a home requires a couple to borrow $210,000 at 7% per year
compounded monthly. The loan is to be repaid in equal monthly payments
over 30 years. The average monthly inflation rate is expected to be 0.4%.
a. What equal monthly payments in terms of constant dollars over the next 30
years is equivalent to the series of actual payments to be made over the life
of the loan?
b. If this were a no-interest loan to be repaid in equal monthly payments over
30 years, what would be the monthly payments in actual dollars?
c. If the inflation rate exceeded the borrowing rate (say, f=10% per year
compounded monthly), find the answer to (a). Compare this result to that of
(b).

9. A firm has an option to purchase 4 years from now a parcel of land that
presently is priced at $250,000. The option states that the price at that time
will be adjusted for inflation, assuming inflation at the rate of 5% per year.
The firm had net earnings last year of $1,000,000, which are assumed to
have occurred at the present. The firm’s earnings are expected to increase
at the rate of 20% per year, and the rate at which they can be invested is
12% compounded annually. What fixed percentage of net earning must be
saved at the end of each next 4 years so that the land can be purchased 4
years from now?

10. An individual is considering an investment in a retirement fund that
earns 14% per year compounded semiannually. He has just celebrated his
40th birthday and he is planning to retire on his 65th. By making equal
semiannual deposits of $2,000 up to and including his 65th birthday, what
equal annual withdrawals in actual dollars could be made beginning on his
65th birthday, the last withdrawal occurring on his 75th birthday? If the
annual inflation rate is 10% compounded semiannually, find the constantdollar equal-annual series over the same 11 years that is equivalent to these
withdrawals. (Constant-dollar base, 40th birthday.)
Answer: $132,898; $7,727.

11. A family borrowed $100,000 and purchased a home 20 years ago. The
loan was for 30 years at 7% compounded annually. The savings and
loan association where the money was obtained is now offering the
following deal. A borrower can pay off a loan now by paying only 85%
of the remaining balance. It is anticipated that the average market rate
of interest will be 12% over the next 10 years. (Assume that payments
on the loan are made annually and the 20th payment has just been
made). Determine whether the borrower should pay the loan off
immediately. The inflation rate is 10% annually.
