Answer:
1 is allowed on the elevator.
2 is allowed on the elevator.
3 is allowed on the elevator.
4 is not allowed on the elevator.
5 is allowed on the elevator.
Step-by-step explanation:
If the maximum weight capacity of the elevator is 750 pounds, then that means every weight that is 750 pounds or less is allowed on the elevator.
1 is allowed because 700lbs is lower than 750lbs, therefore it is safe.
2 is allowed for the same reason, 620lbs is lower than 750lbs.
etc, etc.
So that's all you need to look for :)
