EXERCISES

Exercise B-1 (10 minutes)

In Table B.2, where i = 12% and f = $96,463/$10,000 = 9.6463, the n = 20 (implies the investor must wait 20 years before payment).

Exercise B-2 (10 minutes)

In Table B.2, where n = 25 and f = $108,347/$10,000 = 10.8347, the i = 10% (investor must earn 10% interest to achieve investment goal).

Exercise B-3 (10 minutes)

In Table B.3, where n = 8 and p = $57,466/$10,000 = 5.7466, the i = 8% (investor must earn 8% interest to achieve investment goal).

Exercise B-4 (10 minutes)

In Table B.3, where i = 10% and p = $82,014/$10,000 = 8.2014, the n = 18 (investor expects 18 annual payments to be received).

Exercise B-5 (10 minutes)

In Table B.4, where n = 40 and f = $154,762/$1,000 = 154.762, the i = 6% (investor must earn a 6% rate of interest).

Exercise B-6 (10 minutes)

In Table B.4, where i = 8% and f = $303,243/$10,000 = 30.3243, the n = 16 (investor must make 16 annual payments to achieve investment goal).

Exercise B-7 (10 minutes)

Interest rate per period = 12% annual / 12 months per year = 1% per month

Using Table B.3, where n = 40 and i = 1%, the p = 32.8347. This means:

Loan balance..... / $16,417.35 / (present value of loan = 32.8347 x $500)
Down payment.... / 6,500.00 / (cash)
Total cost...... / $22,917.35

Exercise B-8 (15 minutes)

Semiannual interest payment = $500,000 x 10% x 1/2 = $25,000

Using Table B.1, where n = 30 and i = 4%, the p = 0.3083 (Principal payment)

Using Table B.3, where n = 30 and i = 4%, the p = 17.2920 (Interest payments)

0.3083 x $500,000 = / $154,150 / present value of maturity amount
17.2920 x $ 25,000 = / 432,300 / present value of interest payments
$586,450 / cash proceeds

Exercise B-9 (15 minutes)

Exercise B-11 (15 minutes)

Amount borrowed = / present value of $20,000 at 10% for 3 years
= / $20,000 x 0.7513 (using Table B.1, i = 10%, n = 3)
= / $15,026

Exercise B-15 (15 minutes)

10 years x 4 quarters = 40 interest periods

8% annual / 4 quarters per year = 2% per quarter

In Table B.2, where n = 40 and i = 2%, the f = 2.2080.

Total accumulation = 2.2080 x $7,200 = $15,897.60

Exercise B-16 (15 minutes)

12% annual / 12 months per year = 1% per month

2.5 years x 12 months per year = 30 total months

In Table B.4, where n = 30 and i = 1%, the f = 34.7849.

Total accumulation = 34.7849 x $50 = $1,739.25

Exercise B-17 (15 minutes)

10 years x 4 quarters per year = 40 total quarters

12% annual / 4 quarters per year = 3% per quarter

In Table B.2, where n = 40 and i = 3%, the f = 3.2620.

In Table B.4, where n = 40 and i = 3%, the f = 75.4013.

3.2620 x $100,000 = / $ 326,200 / future value of initial investment
75.4013 x $50,000 = / 3,770,065 / future value of periodic investments
$4,096,265 / future value of fund

Exercise B-18 (15 minutes)

In Table B.2, where n = 9 and i = 7%, the f = 1.8385.
