Breakeven function with TOTALs moving depending where the breakeven cost and quantity fall

[managingcrap]

Hey guys,

I'm trying to figure out a way that I can get the breakeven cost and quantity, given the initial cost. Please see the picture.

Here's how I wish for it to look like. When the initial cost is 30,000 the breakeven is at C. When the IC is at 55,000, the Beven is at E. What i mean is the calculation is moving depending on where the breakeven falls. Please also note that there's a C and D under the the breakeven totals to indicate which letter the breakeven is made/realized/reached. Also, I need to have the word "TOTAL" to follow the point where the breakeven totals are.

In addition, I did some calculation on cells C11 and C12, and D24 and D25. I did this to get the remainder amount and get the initial cost and the total (to the right of the initial cost).

Everything seems complicated to me and don't know what functions or even where to begin.

Please help.
Thanks in advance.
