A certain smoothie A is three-fifths blueberries and 40% raspberries by weight. Another smoothie B is three-quarters banana and one-quarter raspberries by weight. If the mixed smoothie of A and B is 30% raspberries by weight, how much weight of this mixture belongs to smoothie A?	Pick:
A) 10%
B) 33.33%
C) 45%
D) 50%
E) 66.66%
A is 40% raspberries;   B is 25% raspberries.   A and B is 30% raspberries;   30% raspberries in the mixed smoothie of A and B come from 40% raspberries in A and 25% raspberries in B, thus:   0.3(A+B)=0.4A+0.25B --&gt; 0.1A=0.05B --&gt; A/B=1/2 --&gt; A/(A+B)=1/3.   Answer: 33.33%.
