Project Z is estimated to cost $100,000 to be executed linearly across a timeline of 100 days.

After 75 days, the Project Manager finds that 60% of the project is complete and actual costs are $100,000.

What is the (numerical value) Cost Performance Index (CPI) of the project at day 75?

Is the answer favorable? Why or why not?

Please provide all necessary calculations. I have 60,000/75000 = .8, thus unfavorable

I need to double check my answer
