--------
Let "6x" be the # of lbs she can make.
--------
1 part almond ; 2 parts walnuts ; 3 parts raisin
Quantity:
x almonds costs 12x dollars
2x walnuts costs 9*2x = 18x dollars
3x raisins costs 5*3x = 15x dollars
-----
Equation:
12x + 18x + 15x <= 15 dollars
45x = 15 dollars
x = 1/3 dollar
----
Quantity = 6x lb = 2 lb
