I passed calc 1 and calc2 and still don't know how to take 100% of something and mix it with 10 % of another thing and end up with a 35% blend. I'm not saying you are wrong, I'm just saying you can't be right..
Oh, I got it.. You're not talking about coffee, you're talking about caffeine in the coffee. Kona has blah amount of caffeine and the other brand has blah amount of caffeine.. so you take blah and mix blah amount of blah with the blah and then you multiply blah with blah then divide by blah than you diffuse blah with hot water into a mug you should end up with a 35% blahinated coffee...
