Hi,

I am banging my head against the wall trying to figure this out, with no
success:

I currently have, for example:

Sales Cost GM $ GM%
12 10 2 17%

What I need to calculate is the following: What would I need to increase my
sales to if the cost remains at 10 and the GM $ remains at 2, but the GM%
changes to 15%?

Sales Cost GM $ GM%
? 10 2 15%

Any help would be greatly appreciated!
