Schaum’s Outline of Engineering Economics [1215911]

For the data of Problem 9.12 and Table 9-9, and for MARR = 15%, should the computer be purchased? What peripherals should be purchased?

Table 9-1
Comparison	Δi*
Do-Nothing vs. Basic Computer plus Software	16%
Slow vs. Fast Printer	8%
Low- vs. High-Resolution Video Computer Computer with One Disk Drive	13%
vs. Computer with Two Disk Drives	12%
Zero vs. Two Remote Ports	21%

The basic computer plus software, one slow printer, one disk drive, one low-resolution video, and two remote ports should be purchased, since Δi* > MARR for these items. The high-resolution video may be justifiable on the basis of irreducibles, such as operator eye-fatigue, since its Δi* is not that far away from the established MARR.
