From the statement, we know that in a small cargo plane:
• they have 130 lb of cargo aboard,
,
• in addition, they add ,n, boxes weighing 50 lb each,
,
• the plane weight must be at most ,p, pounds.
The total weight of the plane in pounds is:
[tex]w=50n+130.[/tex]
We know that the weight must be at most (less or equal to) p pounds, so we have the inequality:
[tex]\begin{gathered} w\leq p \\ 50n+130\leq p\text{.} \end{gathered}[/tex]
Answer
The inequality that describes this problem is:
[tex]50n+130\leq p[/tex]
