Cici and amatina have a lot of stickers. cici had one-third as many as amatina had, but then amatina gave her six stickers, so now cici has half as many as amatina. how many stickers did each girl start with?

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.
