Consider the following cash flow:

Year	Cash Flow
0	-$100
1	$50
2	$60
3	$70
4	$80
5	140

If the present value is zero, which one of the following is correct?

A. 100 = 50 + 10(A/G,i,5) + 50(P/F,i,5)

B. 1 = [ 50(P/A,i,5) + 10(P/G,i,5) + 50(P/F,i,5) ] / 100

C. 100(A/P,i,5) = 50 + 10(A/G,i,5)

D. None of the equations are correct.

Please show full work and state the reasons clearly!
