Consider the streams of income given in the following table:

End of Year 1 2 3 4 Total Income Stream A B $7,000 $4,000 $6,000 $5,000 $5,000 $6,000 $4,000 $7,000 $22,000 $22,000 a. Find the present value of each income stream, using a discount rate of 5%, then repeat those calculations using a discount rate of 7%. b. Compare the calculated present values and discuss them in light of the fact that the undiscounted total income amounts to $22,000 in each case
