I got a negative NPV.  Is this what everyone else is getting?

[NEAS: In practice, the expected NPV of projects is zero.  Firms have some projects with positive NPV's and some with negative NPV's.  The final exam problems often have negative NPV's.]

I got a positive NPV, I take the initial investment CF to occur at time 0, then each positive CF as occur at time 1, 2, and 3 respectively. I discount the positive CF using real discount rate to arrive at an answer of 1350.81 I could be interpreting the problem wrong because I've never encountered the use of "year 0" before.

[NEAS: If the cash flows are in nominal dollars, we use the nominal dollar discount rate.]
