Someone please help - very confused

Important Note: This page provides text equivalent for the network diagram shown on the page 1. If you're using screen reader assistant, please view this page instead. Schedule Analysis Exercise Perform a forward and backward pass using the network diagram and formulas below. Calculate all early start and finishes and all late start and finishes. Assume the EF for activity J is the LF for activity J. Then, calculate total and free float for each activity. Formulas: EF=(ES+duration)1LS=(LFduration)+1TF=LFEFFF=(ESsuccessorEStarget)targetduration Network Diagram: - Activity A has a duration of 4 days, an early start of day 1. - On the upper path, Activity B has a duration of 7 days. - On one path from Activity B, Activity E has a duration of 4 days. Activity H has a duration of 6 days. - On the other path from Activity B, Activity F has a duration of 3 days. Activity G has a duration of 4 days. - Both upper paths go to Activity I, which has a 1 day duration. - On the lower path, Activity C has a duration of 7 days. Activity D has a duration of 6 days - The final activity for both paths, Activity J, has a duration of 3 days, an early finish of day 25
