During one game, a total of 50 people attended a baseball team’s games. Forty percent and thirty-four percent of the audiences are supporters of the first and second teams, respectively. How many people attended the game did not support either of the teams?
50 x 40/100 = 20 people support the first team.
50 x 34/100 = 17 people support the second team.
So, a total of 20 + 17 = 37 people supported the first and second teams.
Thus, 50 - 37 = 13 people did not support either team.
