Some assumptions are in order: (1) we assume that we can start tomorrow (April 1), (2) everyone works 7 days a week.
Path 1, 5 and 6 are all critical. Path 5 and 6 will have to be crashed to meet the wedding date of April 22.
3. For path 6, we would reduce the time to Receive the Invitations to 5 days (cost $35) and hire help to address Invitations to reduce this time to 2 days (cost $50). This would reduce the path length to exactly 22 days at a cost of $85.
For Path 5, we would reduce the time to Receive Lace to 5 days (cost $25), reduce Clean/Press to 1 day (cost $30), and hire Mrs.Watson 1 day to reduce Sew Dress to 10 (cost $120) days. This would reduce the path length to exactly 22 days at a cost of $175.
The minimum cost to have the wedding on April 22 is $260.
