Let's summarize the information provided:
- Total students = 100
- Total boys = 61
- Total students on soccer teams = 36
- Girls on soccer teams = 19
- Total students on basketball teams = 35
- Boys on basketball teams = 18
From the above data, we can determine the number of boys and girls on each team.
-
Soccer Team:
- Total players on soccer teams = 36
- Girls on soccer teams = 19
- Therefore, boys on soccer teams = Total soccer players - Girls on soccer players \[ \text{Boys on soccer teams} = 36 - 19 = 17 \]
-
Basketball Team:
- Total players on basketball teams = 35
- Boys on basketball teams = 18 (given)
- Therefore, girls on basketball teams = Total basketball players - Boys on basketball players \[ \text{Girls on basketball teams} = 35 - 18 = 17 \]
-
Summarizing Players:
- Total boys counted so far: \[ \text{Boys on soccer} + \text{Boys on basketball} = 17 + 18 = 35 \]
-
Calculating Track Team Players:
- Total boys = 61
- Therefore, boys on the track team: \[ \text{Boys on track} = \text{Total boys} - \text{Boys on soccer} - \text{Boys on basketball} \] \[ \text{Boys on track} = 61 - 17 - 18 = 26 \]
Thus, the number of boys on the track team is \( \boxed{26} \).
