Determine the total estimated cost at completion and estimated cost to complete for the project in Problem 13, assuming the CPI remains the same through the remainder of the job.

Data From Problem 13:

The ACWP at the end of the third week for the project in Problem 11 is \($16,500\) Determine the CPI for the project. 

Data From Problem 11:

11. A project consists of six tasks. Task A is scheduled to begin at the start of Week 1 and finish at the end of Week 4. Task B is scheduled to begin at the start of Week 1 and finish at the end of Week 2. Task C is sched- uled to begin at the start of Week 3 and end at the end of Week 4. Task D is scheduled to begin at the start of Week 1 and end at the end of Week 1. Task E is sched- uled to begin at the start of Week 2 and end at the end of Week 4. Task F is scheduled to begin at the start of Week 4 and end at the end of Week 4. The budgeted cost for Task A is $10,000, for Task B is $2,000, for Task C is $3,000, for Task D is $1,000, for Task E is $6,000, and for Task F is $4,000. At the end of the third week, Task A is 80% complete, Task B is 100% complete, Task C is 40% complete, Task D is 100% complete, Task E is 55% complete, and Task F has not started. What is the SPI for the project at the end of the third week?
