Consider the project summarized in Table $11-8.$ What is the minimum cost project in order to finish in a year? List the activities crashed and the total cost? What is the difference in the total project cost before and after crashing? For the toolbar, press ALT$+$F$10($PC$)$ or ALT$+$FN$+$F$10($Mac$).$
