Answer:
Alex sold 240 white chocolate candy bars
Explanation:
First, you have to write the equations:
m+w= 330
2m+3w= 900
Then, you have to isolate one of the variables in the first equation and replace it on the second equation:
m= 330-w
2 (330-w)+3w= 900
660-2w+3w= 900
w=900-660
w= 240
The number of white chocolate candy bars that Alex sold is 240.
