1. Let's call the amount of her apple cider she will put in each bottle: 
2. You know that she wants to bottle 1\8 of her apple cider and she pours it among 6 bottles.
3. Therefore, keeping the information above on mind, you can write the following expression:

4. When you solve for x, you obtain the following result:

This would be 42 because 17+4•2=42
Let f be the fraction invested at 10%. So (1-f) is the fraction at 7%. After one year the interest is
664 = 8200 f (.10) + 8200 (1-f) (.07) = 8200(.03)f + 8200(.07)
f = (664 - 8200(.07))/(8200(.03)) = .3659 = 36.59 %
Answer: 36.59%
Check:
8200(.3659)*.1 + 8200(1-.3659)*.07 = 664.01 good
