你有＄100，可樂每＄2一瓶，每四個瓶蓋可以多換一瓶，每兩個瓶子又可以多換一瓶，又或者可以用一個瓶子和兩個蓋子換一瓶，直至你換得超過100瓶，則轉為六個蓋子／三個瓶子換取一瓶（不能同時用瓶子和蓋子換），最多能換+買多少瓶？

It is my first time to offer question.

Although some of you may think that it is same as http://gameschool.cc/puzzle/2484/, but it is totally different. (Of course, I will not only change the no. and said that it is different)
