Calculation Problem

[charlee63]

Excel 2010
	A	B	C	D
1	OC	TM	MU	Total Cost
2	28.89	1.92	7%	32.96
3		1.92	7%	32.96

<COLGROUP><COL style="WIDTH: 48pt" span=5 width=64><TBODY>
</TBODY>

Row 2 Is Calculated By A2+B2+((A2+B2)*C2)
The Problem Is I TM, MU and Total Cost I need to calculate OC.
What is the Formula to do this?

<COLGROUP><COL style="WIDTH: 48pt" width=64><TBODY>
</TBODY>

if I read your formula right:

D=(A+B)*(C+1)
so
A=D/(C+1)-B
