Present Value--Mixed Streams

Consider the mixed streams of cash flows shown in the following table:

a.Find the present value of each stream using a 3% discount rate.

b.Compare the calculated present values and discuss them in light of the undiscounted cash flows totaling $40,000 in each case. Is there some discount rate at which the present values of the two streams would be equal?

Thank you in advance!!
