Answer:
Cost performance index is 81.25%
Step-by-step explanation:
Actual cost = $80,000
Planned value = $70,000
Earned value = $65,000
Cost performance index (CPI) is the ratio of earned value to actual cost and can be used to estimate the projected cost of completing the project.
CPI = EV / AC
= $65,000 / $80,000
= 0.8125
= 0.8125 x 100
= 81.25%
