A small cargo plane currently has 150 pounds of cargo aboard. In addition, n boxes weighing 30 pounds each will be brought aboard.
Suppose that the total weight of the cargo on board must be at most p pounds. Using the values and variables given, write an inequality describing this.


  1. Answer: 150+30n ≤ p
    Step-by-step explanation:
    150 is your starting amount, and you add 30 lbs of how many ever boxes (n) onto your plane. So far, you have 150 + 30n. Because there is a limit of p amount that you can’t exceed, you need a less than or equal to sign because it can be p amount but not over p amount. So your answer is 150 +30n ≤ p
