Use Cross multiplication....95.6X = 8500

Therefore X = 88.9121% Ethanol, and 11.0879% Gasoline to make E85.

I am such a nerd... or is it the fact that I do this stuff every day at work?
K, here's what I did in my head in 10 seconds:

100.0% - 95.6% = 4.4%

85.0(4.4%) = 3.74

85.0% + 3.74 = 88.74%

Yes, you're a n3rd. But so am I, so it's OK. We can be n3rd-fr3nz
