To answer this item, we let x be the number of stickers Amatina had. With this representation, the number of stickers Cici had can be represented by the expression x/3. The equation that best represent the second scenario is,
(1/2)(x - 6) = x/3 + 6
The value of x from the equation is 54. Therefore, Amatina initially had 54 tickets and Cici initially had 18 stickers.
