Answer:
Givens
- 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
![56b+140\leq 2000](https://img.qammunity.org/2020/formulas/mathematics/high-school/qn2d46aces62f2icscn4s7dbv60dizvwj0.png)
Because the sum of the total weght must be equal or under 2000.
Then, we solve for

![56b+140\leq 2000\\56b\leq 2000-140\\b \leq (1860)/(56)\\ b\leq 33](https://img.qammunity.org/2020/formulas/mathematics/high-school/lloru33izbut8zt9mducr4i05b4kraf03o.png)
Therefore, Teddy can deliver 33 boxes of paper, because that's the maximum allowed in an elevator.
