Given the cash flows for two projects below, find the NPV difference at a WACC of 11%.

Cash Flow	Project Alpha2	Project Beta2
Year 0	-$28,000	-$50,000
Year 1	$15,000	$22,000
Year 2	$20,000	$18,000
Year 3	$12,000	$16,000
Year 4	$10,000	$12,000
Year 5		$10,000

Requirements:

1. Calculate the NPV for each project.
2. Determine the IRR for each project.
3. Compute the equivalent annual annuity (EAA) for each project.
4. Compare the projects and choose the better option based on NPV and IRR.
