...Everything else figured out..? I have to do a project. And I'm stuck on the last part. I have to come up with a percentage formula that equals out to be 14% Grand Total on the first one.. And then I would use the same formula to do the rest. C5 (2.99)-Cost and Unit, D5(25)- Number of Units, E5(74.75)- Total Cost. I came up with =(C5/D5/E5)*100 .. But that equals out to be 16%. I'm stuck. Will someone please help me. Thank you.
