P4-25 Value of a mixed stream
For each of the mixed streams of cash flows shown in the following table, determine the future value at the end of the final year if deposits are made at the beginning of each year into an account paying annual interest of 12%, assuming that no withdrawals are made during the period.
Cash flow stream
Year A B C
1 \$ 900 \$30,000 \$1,200
2 1,000 25,000 1,200
3 1,200 20,000 1,000
4 10,000 1,900
5 5,000

P4-31 Relationship between future value and present value?Mixed stream
Using only the information in the accompanying table, answer the questions that follow.
Year (t) Cash flow Future value interest factor at 5% (FVIF5%,n)
1 \$ 800 1.050
2 900 1.102
3 1,000 1.158
4 1,500 1.216
5 2,000 1.276
A) Determine the present value of the mixed stream of cash flows using a 5% discount rate.
B) How much would you be willing to pay for an opportunity to buy this stream, assuming that you can at best earn 5% on your investments?
C) What effect, if any, would a 7% rather than a 5% opportunity cost have on your analysis? (Explain verbally.)

P4-37 Annuities and compounding
Janet Boyle intends to deposit \$300 per year in a credit union for the next 10 years, and the credit union pays an annual interest rate of 8%.
A) Determine the future value that Janet will have at the end of 10 years, given that end-of-period deposits are made and no interest is withdrawn, if
a. \$300 is deposited annually and the credit union pays interest annually.
b. \$150 is deposited semiannually and the credit union pays interest semiannually.
c. \$75 is deposited quarterly and the credit union pays interest quarterly.
B) Use your finding in part a to discuss the effect of more frequent deposits and compounding of interest on the future value of an annuity.

P4-43 Loan amortization schedule
Joan Messineo borrowed \$15,000 at a 14% annual rate of interest to be repaid over 3 years. The loan is amortized into three equal, annual, end-of-year payments.
A) Calculate the annual, end-of-year loan payment.
B) Prepare a loan amortization schedule showing the interest and principal breakdown of each of the three loan payments.
C) Explain why the interest portion of each payment declines with the passage of time.

P4-51 Interest rate for an annuity
Anna Waldheim was seriously injured in an industrial accident. She sued the responsible parties and was awarded a judgment of \$2,000,000. Today, she and her attorney are attending a settlement conference with the defendants. The defendants have made an initial offer of \$156,000 per year for 25 years. Anna plans to counteroffer at \$255,000 per year for 25 years. Both the offer and the counteroffer have a present value of \$2,000,000, the amount of the judgment. Both assume payments at the end of each year.
A) What interest rate assumption have the defendants used in their offer (rounded to the nearest whole percent)?
B) What interest rate assumption have Anna and her lawyer used in their counteroffer (rounded to the nearest whole percent)?
C) Anna is willing to settle for an annuity that carries an interest rate assumption of 9%. What annual payment would be acceptable to her?

2. Calculate the firm's EBIT at 9,000, 10,000, and 11,000 units, respectively.
3. With 10,000 units as a base, what are the percentage changes in units sold and EBIT as sales move from the base to the other sales levels used in part b?
4. Use the percentages computed in part c to determine the degree of operating leverage (DOL).
5. Use the formula for degree of operating leverage to determine the DOL at 10,000 units.
