------------
Equation:
sugar + sugar = sugar
0.43*11 + 0.34*12 = (x/100)(11 + 12)
------------------------------------------
43*11 + 34*12 = 23x
-------
Ans:: 38.3%

The emphasis is on concentration of sugar.

percent sugar VOLUME pure sugar cranberryjuice p 11 0.01*11*p applejuice 34 12 0.34*12 MIXTURE 43 23 0.43*23

One way to use this is to account for the amount of pure sugar although the actual way
the concentrations are used is not too clear. Was that as mass per volume? This would
not be appropriate with such high concentrations of sugar. The rest of this problem-solving
may be faulty because of this need for the right kind of percentage. Sugar itself would
be a solid, so counting it in mass would be used. Your description did not say. The concentration
must either be volume per volume (which makes no sense here), or mass per mass (but no density were
given), or mass per volume (but this seems poor to use for such high sugar concentrations).

Going ahead with just the arithmetic, accounting for the sugar:

Solve for p.
