Answer 1

Answer:

$\boxed{\textsf{ The number of Teachers that attented is \textbf{ 164 } .}}$

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:-

$\sf\implies n(students) = 386$

Number of parents :-

$\sf\implies n(parents) = 212$

Number of teachers :-

$\sf\implies n(teachers) = ?$

Here the Number of teachers could be simply find out by subtracting the number of students and teachers from the total number of attendees .

$\sf\implies n_{(teachers)}= n_{(total)}- n_{(students)}- n_{(parents)} \\\\\sf\implies n_{(teachers)}= 762 - 386 - 212 \\\\\sf\implies n_{(teachers)}= 762 - 598 \\\\\sf\implies\boxed{\pink{\frak{ n_{(teachers)}= 164 }}}$
