Clearly identify all alternatives (your model should evaluate three alternatives). Construct an NPW or EUAW (or EUAC) graph showing all alternatives...

$12,000

1. Compute NPW of each alternative
2. Generate an NPW graph with NPW on the Y-axis and interest rate on the X-axis with all alternatives on one graph (see Figure 8-6 for an example).
3. Generate an EUAW graph (see figure 8-5 for an example).
4. Construct a choice table for interest rates from 0% - 100%.
5. Using a MARR of 15% and a rate of return analysis, which alternative, if any, should be selected?  

I need help with this Excel spread sheet.

Thanks
