acid in 60 ml of a 25% acid solution in water to 35% acid, how much pure acid must you add

You can put this solution on YOUR website!
{amount of acid}/{amount of solution}={concentration of solution}

v = amount of pure acid to add, BY VOLUME!
%2860%2A25%2Bv%2A100%29%2F%2860%2Bv%29=35
Solve for v.
