Hello,
Here is the question from PMP Exam Prep app:
You're managing a construction project to install several hundred air conditioner panels in a new office building. You have completed 350 panels out of a total 900 panels, but according to your schedule you should have completed 400 of them. Your company's contract states that you'll be paid a fixed price of $75 per panel. You've spent $45,000 so far on the project. Which of the following BEST describes your situation?
a) The CPI is .813, which means your project is currently over your budget
b) the CV is -$4,350, which means your project is currently over your budget
c) the TCPI is 1.833, which is the minimum CPI you need to stay within budget
d) the SPI is .84, which means your project is behind schedule
C is considered to be a correct answer. But why? And how it is possible to calculate TCPI based on the information provided? And why 1.833 is the minimum CPI you need...? Pls advise!
