Question 45 on the 2011 PM mock exam... I did it the NPV method (or tried) and my calc gave me an NPV of 153K (more than the accelerated method). Is it a setting on my calc? I get 146445 (the amount given for the accelerated method) when I plug in the npvs in the second exhibit though so its really annoying me right now.
