A small auditorium can seat 320 people which inequality best reprsents the number of people ,p, who can sit in the auditorium

Jet001 [13]

Answer: The answer is $0\leq p\leq 320.$

Step-by-step explanation: Given that in a small auditorium, 320 peoples can sit. The number of peoples who can sit in the auditorium is represented by 'p'.

Since no more that 320 people can sit in the auditorium, so the number of persons who can sit there lies between 0 and 360.

Therefore, the inequalities are

$p\geq 0~~~\textup{and}~~~p\leq 360.$

Combining both of the above inequalities, we get

$0\leq p\leq 360.$

Thus, the required inequality is $0\leq p\leq 360.$ .
