Answer:

- Each box weighs 56 pounds.
- Teddy weighs 140 pounds.
- The maximum capacity of the elevator is 2,000 pounds.
So, we have 56 pounds per box, this can be expressed as
, where
represents boxes.
This problem is about a restriction as maximum, that means we need to use the inequality sign
, which represents all values accepted.
Taking in count all those details, the inequality expression is

Because the sum of the total weght must be equal or under 2000.
Then, we solve for


Therefore, Teddy can deliver 33 boxes of paper, because that's the maximum allowed in an elevator.
