What is the EAC (Equivalent Annual Cost) of the following stream of expenses? Assume an interest rate of 12%. Here I want you to evaluate all of the costs in determining the EAC, not just the time zero cost. \begin{tabular}{|l|l|} \hline Period 0: & ($50,000) \\ \hline Period 1: & ($30,000) \\ \hline Period 2: & ($40,000) \\ \hline Period 3: & ($30,000) \\ \hline \end{tabular}
