b. If your discount rate is 4.7 %, what are the NPVs of the two projects?

c. Why do IRR and NPV rank the two projects differently?

\begin{tabular}{cccccc} Project & Year 0 & Year 1 & Year 2 & Year 3 & Year 4 \\ \hline A & $51 & $24 & $20 & $22 & $17 \\ B & $102 & $20 & $41 & $51 & $60 \\ \hline \end{tabular}
