i think it’s is a for the first one
Not sure if this is what you need
Answer:
The last one
Step-by-step explanation:
x can only have one value whereas y can be constants like in last graph
From all the math I’ve done it does not seem that any of them a correct
The number of seats sold cannot be negative, so you have
... x ≥ 0, y ≥ 0
The limits on numbers of seats must be observed, so you have
... y ≤ 2000
... x + y ≤ 3000
And the revenue constraint must be met:
... 35x + 50y ≥ 90,000
Together, these inequalties are ...
{x ≥ 0, y ≥ 0, y ≤ 2000, x + y ≤ 3000, 35x + 50y ≥ 90,000}
