Ok this is the first problem i already answered Chapter 3. On a Thursday, Jeanie decided that she would like to have a dinner party for a few of her colleagues and was wondering if Saturday was a feasible day to have the party or not. She wanted to get an idea of how many hours of work she would need to do to make a reasonably fancy dinner ready by 6 PM on Saturday. She decided to create a project network based on the activities she thought were essential for doing this. Help her identify the critical path by creating a project network and activity schedule (show work in your submission file in the last question of this problem set) and answer the following questions.
