Joe Hernandez has inherited $25,000 and wishes to purchase an annuity that will provide him with a steady income over the next 12 years. He has heard that the local savings and loan association is currently paying 6 percent compound interest on an annual basis. If he were to deposit his funds, what year-end equal-dollar amount (to the nearest dollar) would he be able to withdraw annually such that he would have a zero balance after his last withdrawal 12 years from now? 4. You need to have $50,000 at the end of 10 years. To accumulate this sum, you have decided to save a certain amount at the end of each of the next 10 years and deposit it in the bank. The bank pays 8 percent interest compounded annually for long-term deposits. How much will you have to save each year (to the nearest dollar)?
Business Finance 5. Same as Problem 4 above, except that you deposit a certain amount at the beginning of each of the next 10 years. Now, how much will you have to save each year (to the nearest dollar)? 6. Vernal Equinox wishes to borrow $10,000 for three years. A group of individuals agrees to lend him this amount if he contracts to pay them $16,000 at the end of the three years. What is the implicit compound annual interest rate implied by this contract (to the nearest whole percent)? 7. You have been offered a note with four years to maturity, which will pay $3,000 at the end of each of the four years. The price of the note to you is $10,200.

7 $1,400
8 $1,400
9 $1,400
10 $1,400
Cash flow If the appropriate annual discount rate is 14 percent, what is the present value of this cash-flow stream? 10. Suppose you were to receive $1,000 at the end of 10 years. If your opportunity rate is 10 percent, what is the present value of this amount, if interest is compounded (a) annually? (b) quarterly? (c) continuously? 11. In connection with the United States Bicentennial, the Treasury once contemplated offering a savings bond for $1,000 that would be worth $1 million in 100 years. Approximately what compound annual interest rate is implied by these terms? 12. Selyn Cohen is 63 years old and recently retired. He wishes to provide retirement income for himself and is considering an annuity contract with the Philo Life Insurance Company. Such a contract pays him an equal-dollar amount each year that he lives. For this cash-flow stream, he must put up a specific amount of money at the beginning. According to actuary tables, his life expectancy is 15 years, and that is the duration on which the insurance company bases its calculations regardless of how long he actually lives. a. If Philo Life uses a compound annual interest rate of 5 percent in its calculations, what must Cohen pay at the outset for an annuity to provide him with $10,000 per year? (Assume that the expected annual payments are at the end of each of the 15 years.) b. What would be the purchase price if the compound annual interest rate is 10 percent? c. Cohen had $30,000 to put into an annuity. How much would he receive each year if the insurance company uses a 5 percent compound annual interest rate in its calculations? A 10 percent compound annual interest rate?
Business Finance 13. The Happy Hang Glide Company is purchasing a building and has obtained a $190,000 mortgage loan for 20 years. The loan bears a compound annual interest rate of 17 percent and calls for equal annual installment payments at the end of each of the 20 years. What is the amount of the annual payment? 15. You have borrowed $14,300 at a compound annual interest rate of 15 percent. You feel that you will be able to make annual payments of $3,000 per year on your loan.

It makes a bid to the government to participate in the development of a mine, the profits of which will be realized at the end of five years. The mine is expected to produce $5 million in cash to Lost Dutchman Mines at that time. Other than the bid at the outset, no other cash flows will occur, as the government will reimburse the company for all costs. If Lost Dutchman requires a nominal annual return of 20 percent (ignoring any tax consequences), what is the maximum bid it should make for the participation right if interest is compounded (a) annually? (b) semiannually? (c) quarterly? (d) continuously? 17. Earl E. Bird has decided to start saving for his retirement. Beginning on his twenty-first birthday, Earl plans to invest $2,000 each birthday into a savings investment earning a 7 percent compound annual rate of interest. He will continue this savings program for a total of 10 years and then stop making payments. But his savings will continue to compound at 7 percent for 35 more years, until Earl retires at age 65. Ivana Waite also plans to invest $2,000 a year, on each birthday, at 7 percent, and will do so for a total of 35 years. However, she will not begin her contributions until her thirty-first birthday. How much will Earl’s and Ivana’s savings programs be worth at the retirement age of 65? Who is better off financially at retirement, and by how much? 18. When you were born, your dear old Aunt Minnie promised to deposit $1,000 in a savings account for you on each and every one of your birthdays, beginning with your first.

(f) continuously? 22. It took roughly 14 years for the Dow Jones Average of 30 Industrial Stocks to go from 1,000 to 2,000. To double from 2,000 to 4,000 took only 8 years, and to go from 4,000 to 8,000 required roughly 2 years. To the nearest whole percent, what compound annual growth rates are implicit in these three index-doubling milestones?
