Consider the following two mutually exclusive projects: \begin{tabular}{|c|c|c|} \hline Year & Cash Flow (X) & Cash Flow (Y) \\ \hline 0 & $30,000 & $30,000 \\ 1 & $13,700 & $15,600 \\ 2 & $14,200 & $12,200 \\ 3 & $13,400 & $13,300 \\ \hline \end{tabular} a) Calculate the IRR for each project. Use Excel Project X Project Y b) What is the crossover rate for these two projects. Use Excel Crossover rate
