The capital fund for new investment at Systems Corporation is limited to $75,000 for next year. You have been asked to recommend one or more of three projects as economically acceptable for investment at the corporate MARR of 15% per year. Perform the analysis in two ways: (a) by hand, and (b) using NPV functions and a spreadsheet.

(a) By hand
Sample calculations of PW for bundles
PWA = -25,000 + 6000(P/A,15%,4) + 4000(P/F,15%,4)
= -25,000 + 6000(2.8550) + 4000(0.5718)
= $-5583
PWA,B = -55,000 + 15,000(P/A,15%,4) + 3000(P/F,15%,4)
= -55,000 + 15,000(2.8550) + 3000(0.5718)
= $-10,460
