Dave Fletcher was able to determine the activity time for constructing his laser scanning machine. Fletcher would like to determine ES, EF, LS, LF and SLACK for each activity. The total project completion time and the critical path should also be determined. Here are the activity times:
What is the ES for Activity A if the EF time is 5?
