Real-Life Math

You're an elevator repair technician who has been called to an emergency where a number of people are stuck in an elevator. The lights have gone out on the display panel, so you don't know where the elevator has stopped.

One person managed to squeeze out the elevator doors before they slammed shut and jammed. Panicked, the person ran down the stairs to the first floor to try and get help. Unfortunately, he didn't remember what floor he was on when the elevator stuck.

He does remember that he started his ride at the 4th floor, and went down 5 floors in the elevator. Realizing he was at the wrong floor, he then went up 8 floors, where the elevator got stuck. At which floor is the elevator stuck?

You think that the stuck elevator may have been overloaded. The capacity for the elevator is 11 persons. This weight limit is calculated by estimating that each person weighs 160 pounds. If the total mass in the stuck elevator is 1,960 pounds, how many pounds over capacity is it?
