6. Determine the estimated cost of the work performed cach weck given the tasks - with their associated costs and schedules - shown in the following table (Table 7-4). When a task spans more than one week, the costs should be divided equally among the weeks.

Task Bis scheduled to begin at the start of Week 1 and finish at the end of Week 2 Task C is scheduled to begin at the start of Week 3 and finish at the end of Week 4. Task Dis scheduled to begin at the start of Weck I and end at the end of Week 1 Task Eis scheduled to start at the beginning of Week 2 and end at the end of Week 4. Task Fis schedule to begin at the start of Week 4 and at the end of Week 4. The budgeted cost for Task A is $10,000. Task Bis $2.000, for Task C is $3,000 for Task Dis 1.000. for Task Eis 56,000 and for Task Fis $4,000. At the end of the third week. Task A is 80%. Task B is 100% complete. Task C is 40% complete. Task Dis 100%. Task Eis 55% complete and Task Fhas not yet started. What is the SPI for the project at the end of the third week! b. The ACWP at the end of the third week for the project is $16.00. Determine the CPI for the project. c. Determine the total estimated cost at completion and estimated cost to complete for the project assuming the CPt remains the same through the remainder of the job 8.
