During one month at a particular restaurant, 1/6 of the burgers sold were veggie burgers and 1/2 of the rest of the burgers sold were double-meat. If x of the burgers sold were double-meat, how many were veggie burgers?  Choices:  A) x/8  B) x/2  C) 2x/5  D) 3x/4  E) 4x/5
Let y be the number of total burgers.   veggie = y/6 , non veggie = 5y/6   1/4 of the rest of the burgers sold were double-meat   =&gt; 5y/6 * 1/2 = double meat = x   =&gt; y/6 = 2x/5 = veggie   Hence 2x/5
