Not sure if this is right, but 30% acid is 5% away from Solution A, and 10% away from Solution B, so I figured the ratio needed of Solution A:Solution B was 2:1. I then did 2x+x=60 x=20 since the ratio is 2x:x, it is also 40:20. 40 liters Solution A, 20 liters Solution B.

ln e^lnx-ln(x-3)=ln8 First of all the "ln of e" cancels out, so it is just: ln(x)-ln(x-3)=ln(8) which is the same as: ln(x/(x-3))=ln(8) e^ both sides... x/(x-3)=8 x=8x-24 7x=24 x=24/7
