integer 3 represents elevator final position with respect to the main floor.

Step-by-step explanation:

Given : An elevator starts at the main floor and goes up 8 floors. It then goes back down 5 floors.

To find : What integer represents elevator final position with respect to the main floor.

Solution : We have given

Elevator starts at the main floor and goes up floors = + 8 (for up).
