The following costs have been estimated for the activities in a project:

(a) Develop a cost schedule based on earliest start times.

(b) Develop a cost schedule based on latest start times.

(c) Suppose that it has been determined that the $6,000 for activity G is not evenly spread over the 3 weeks. Instead, the cost for the first week is $4,000, and the cost is $1,000 per week for each of the last 2 weeks. Modify the cost schedule based on earliest start times to reflect this situation.
