Common-sized Calcuations

I have a feeling I’m going to feel really foolish when I the solution.

I’ve hit a mental block on the formula for common sizing a simple P&L that I’ve attached.

I’ve tried two variations and yield the same results. The output is [b:233rsrt0]CORRECT[/b:233rsrt0], but not only does the formula not look right, the formula is being flagged.

I’m using version 6. If you have not upgraded, I will add a second message below for the screenshot. This forum does not appear to allow more than one file attachment.

Yes, I’m preparing myself to be embarrassed when I see the right solution.
