Answer:
![130+40n\leq p](https://tex.z-dn.net/?f=130%2B40n%5Cleq%20p)
Step-by-step explanation:
We have been given that a small cargo plane currently has 130 pounds of cargo aboard. In addition, n boxes weighing 40 pounds each will be brought aboard.
The weight of n boxes would be
.
The total weight of the cargo on board would be initial weight plus weight of n boxes.
![130+40n](https://tex.z-dn.net/?f=130%2B40n)
The total weight of the cargo on board must be at most p pounds. This means that total weight of the cargo must be less than or equal to p.
We can represent this information in an inequality as:
Therefore, our required inequality would be
.
