please help I don't understand this at all, here is the chart to refer to, ill give you extra ratings!

For the network below, calculate for each task, BCWP, BCWS, ACWP, CV, SV, CPI, SPI.
Calculate these numbers for the entire project as well.
For each of the seven tasks that make up the project above, assume the following:
	TASK	Percent Complete	Expenditures/Day	Actual Expenditures to Date	Duration
	A	100%	$1,000	$13,000	10
	B	100%	$1,200	$9,000	9
	C	30%	$1,000	$4,000	7
	D	20%	$1,500	$5,000	6
	E	40%	$1,500	$3,000	5
	F	0%	$1,000	$0	9
	G	0%	$1,200	$0	4
Fill out the table below:
TASK	TOTAL BUDGET	%COMP	ACWP	BCWS	BCWP	CV	SV	CPI	SPI
			(AC)	(PV)	(EV)
A	$10,000	100%	$13,000
B		100%	$9,000
C		30%	$4,000
D		20%	$5,000
E		40%	$3,000
F		0%	$0
G		0%	$0
