Tiffany's Triumphs

     Tiffany plays first board on her middle school's chess team. She had a good record last semester, winning 60% of her 50 tournament games.

     After diligent study and lots of practice during the summer vacation, she has recently been on a hot streak this semester, winning 3 out of every 4 games she has played. At the end of this winning streak, she had won two-thirds of all her games so far.

     How many total games has she played in both semesters?
