If you donate say an extra 5% to a fundraiser is that after the 15% or with the 15%. I hope I'm making myself clear. If the fundraiser is $3000 their earnings would be $450 if you donate the 5% is it 15% & then another 5% to make it $22.50 or is it a total 20% to make it $600. I know I'm probably confusing you, but I need to figure this out so I can do this. Thanks
