i know its 162 seats in the auditorium but im not sure what the estimate is cause sometimes the estimate can be off from the answer.

the solution is x=1

step-by-step explanation:

let's assume

left side function is

right side function is

now, we can draw graph

and then we can get intersection point

the intersection point will be solution

so, the solution is

x=1
