Hi, I’m working on CFAI 2010 Mock Q33 on the John Earl case. I cannot seem to match the NPV difference answer stated of 4,445 between using straightline vs accelerated deprecation… I end up getting a NPV of 123373.2482 instead. t0 - t5 cashflows -185000 60000 57520.66116 56348.61007 56143.70603 78360.27097 Thanks.
