A certain factory produces buttons and buckles at a uniform weight. If the total weight of 2 buttons and 2 buckles is one third of 11 buckles and 3 buttons, then the weight of 3 buttons and 6 buckles is how many times that of 5 buckles and 6 buttons?	Choose the correct choice:
A) 7/15 B) 2/5 C) 8/15 D) 3/5 E) 11/15
Let x be the weight of a button and let y be the weight of a buckle.   2x + 2y = (1/3)(3x+11y)   3x = 5y   x = 5y/3   3x + 6y = a(6x+5y)   11y = a(15y)   a = 11/15   The answer is 11/15.
