Question 303516
no, not remotely


if you mixed equal amounts of the two solutions; the strength of the resulting mixture would be the average
___ in this case, 12 ounces of 8%
___ so the stronger solution must be more than half of the mixture


(4%)(x) + (12%)(12 - x) = (9%)(12)


4x + 144 - 12x = 108


36 = 8x


4.5 = x


4.5 oz of 4% and 7.5 oz of 12%
