Answer 1

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

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 }}}`
