Determine which of the following independent projects should be selected for investment if a maximum of $240,000 is available and the MARR is 10% per year. Use the PW method to evaluate mu­tually exclusive bundles to perform your analysis.


Develop bundles with less than $240,000 investment; select the one with the largest PW.



PW1 = -100,000 + 50,000(P/A,10%,8)

= -100,000 + 50,000(5.3349)

= $166,746



PW2 = -125,000 + 24,000(P/A,10%,8)

= -125,000 + 24,000(5.3349)

= $3,038



PW3 = -120,000 + 75,000(P/A,10%,8)

= -120,000 + 75,000(5.3349)

= $280,118



PW4 = -220,000 + 39,000(P/A,10%,8)

= -220,000 + 39,000(5.3349)

= $-11,939



PW5 = -200,000 + 82,000(P/A,10%,8)

= -200,000 + 82,000(5.3349)

= $237,462



All other PW values are obtained by adding the respective PW for bundles 1 through 5.



Conclusion: Select PW = $446,864, which is bundle 7 (projects A and C) with $220,000 total investment.
