Please show how you got PV and IRR

Consider two streams of cash flows, A and B. Stream As first cash flow is $8,900 and is received three years from today. Future cash flows in Stream A grow by 4 percent in perpetuity. Stream Bs first cash flow is $10,000, is received two years from today, and will continue in perpetuity. Assume that the appropriate discount rate is 12 percent.

a.	What is the present value of each stream?(Negative amounts should be indicated by a minus sign. Do not round intermediate calculations and round your final answers to 2 decimal places. (e.g., 32.16))

	Present value
Stream A	$
Stream B	$

b.	Suppose that the two streams are combined into one project, called C. What is the IRR of Project C?(Do not round intermediate calculations and round your final answer to 2 decimal places. (e.g., 32.16))
