How do i calculate the SPI, CPI, PCI-B, TCPI, EACf, VACf ?

You have been provided with the following revised estimates for the remainder of the project: Activity H will be completed at the end of period 12 at a total cost of 600 Activity I will be completed at the end of period 12 at a total cost of 750 Activity J will be completed at the end of period 14 at a total cost of 500 Base on the revised estimates, what is the Estimated Total Cost at Completion (FACrc) (round your response to the nearest whole number)? Base on the revised estimates, what is the Variance at Completion (VACrc) (round your response to the nearest whole number)? Based on the data provided in the Period 8 Status Report below answer questions 5 through 10. After period 8, what is the Scheduling Performance Index (SPI) value (round your response to two decimal places)? After period 8, what is the Cost Performance Index (CPI) value (round your response to two decimal places)? .After period 8, what is the Percent Complete Index based on Budget .Amounts (PCI-B) (round your response to the nearest whole percent)? After period 8, what is the To Complete Performance Index (TCPI) (round your response to two decimal places)? After period 8, what is the forecasted Estimated Total Cost at Completion(FACr) (round your response to the nearest whole number)? After period 8. what is the forecasted Variance At Completion VAC&) (round your response to the nearest whole number)
