  33. The University of Georgia and Florida State University scored a total of 39 points during the 2003 Sugar Bowl. The points came from a total of 11 different scoring plays, which were a combination of touchdowns, extra – point kicks, and field goals, worth 6, 1, and 3 points respectively. The same numbers of touchdowns and field goals were scored. How many touchdowns, extra – point kicks, and field goals were scored during the game? (Source: espn.com) D 300
