I come up with 2 different solution for this problem, however neither seem to be correct becuase when I try and confirm the answer back with known values they don't match. Please respond with details and explain steps so I can see where I went wrong. Thank you in advance. P. S. any answer taken from other sources will be reported as NOT HELPFUL.

Our project is running as planned. The following are the latest results: -CPI= 1.3 SPI = 0.9 -PV= 6000 -SV= -1300 Calculate EV and AC option 1 option 2 SV = EV - PV SPC = EV / PV EV = SV + PV EV = SPI X PU = - 1300+ 6000 = 0. 9 x 6000 470 0 $ 5400 CPI = EVAC CPI = FU/AL AC = EV / LPI AL = EV / CPI = 4700 - 1 13 = 5400 7 1,3 2 36 151 38 4153 - 846 SPI = EV = PV SV = EV - PV = 4700 = 6000 - 5400- 6000 7 0. 7833 7 - 600 SPI supposed to = 0 . 9 SV suppose to = - 1300
