Answer:
[tex]\boxed{\textsf{ The number of Teachers that attented is \textbf{ 164 } .}}[/tex]
Step-by-step explanation:
Here it's given that a total of 762 people consisting of parents, students, and teachers, attended the Community Fair. There were 212 parents and 386 students at the fair .That is ,
Number of students:-
[tex]\sf\implies n(students) = 386 [/tex]
Number of parents :-
[tex]\sf\implies n(parents) = 212 [/tex]
Number of teachers :-
[tex]\sf\implies n(teachers) = ? [/tex]
Here the Number of teachers could be simply find out by subtracting the number of students and teachers from the total number of attendees .
[tex]\sf\implies n_{(teachers)}= n_{(total)}- n_{(students)}- n_{(parents)} \\\\\sf\implies n_{(teachers)}= 762 - 386 - 212 \\\\\sf\implies n_{(teachers)}= 762 - 598 \\\\\sf\implies\boxed{\pink{\frak{ n_{(teachers)}= 164 }}}[/tex]
