Consider the streams of income given in the following table:

Income Stream

End of Year A B

1 $9,000 $6,000

2 $8,000 $7,000

3 $7,000 $8,000

4 $6,000 $9,000

Total $30,000 $30,000

a. Find the present value of each income stream, using a discount rate of 1 %, then repeat those calculations using a discount rate of 9%

b. Compare the calculated present values and discuss them in light of the fact that the undiscounted total income amounts to $30,000 in each case.
