I came up with a different example, Jack wants to buy 4 pumpkins, but he needs to know how much the pumpkins cost so he doesn't spend more than $25. 4p ≤ 25 4p/2 ≤ 25/4 p=6.25 p ≤ $6.25 is this right?

Give a real-world scenario in which you would write an inequality rather than an equation. I was thinking, Jack has to bring at least $25 to a carnival. So the inequality would be x ≥ 25? or could you help me with a different example?
