Set up a simple equation. Let "c" = cargo. Cargo is a variable because it is unknown.

$$4(180) + c \le 1128$$

why did u choose this sign ≤. I want to know because I'm confused
My I solve this equation and my answer is C ≤408 IS IT CORRECT

anonymous · Answer

Yes, your solution is correct. You choose less than or equal to because the total weight of the cargo and passengers must be LESS than the weight limit (maximum weight)

anonymous · Answer

Well, less then or equal to. I think strictly less than would be appropriate.
